I assume these are the original rims. 14 inch ralleye's. I've seen discussions on here about the red & black PMD center caps. These are chrome with the Pontiac logo on them. Car only has 3 of them tho. Are these 6inch &7inch rims? Front & rear. What would the original tire sizes be? In radial sizes. Not the F70 bias ply sizes. It has 245/60R14s on the rear & 215/75/R14s on the front right now. I'm gonna sand blast & re-paint the rims & put some BF Goodrich T/A radials on her this winter

Regarding wheels - this is where some sort of documentation helps;
The Formula model came standard with blackwall F70-14 tires - this tire size required 7” wide wheels.
If no wheel option was ordered, then the 1970 Formula Firebird came standard with plain steel wheels (normally painted body colour) with small “dog dish” caps.

It is generally accepted that an F70-14 converts to a 225/70R14 tire size.

White letter tires were optional, as were Rally wheels;
Both of these were separate options.
Also optional was 15” (F60-15) tires - this option required Rally II wheel option.

If no wheel option was selected, the car did not come with trim rings;
So trim rings were a stand alone option without optional wheels.
If rally wheels were opted, they included trim rings.

Wheel codes are:
14x7” steel ‘CL’
14x7” Rally II ‘JS’
15x7” Rally II ‘JW’

Black (background color) PMD caps were used on early 1970 model year production models - NOT Firebirds;
1970 Firebirds (and Camaros) were only released in February 1970;
The rally wheel cap was changed prior to January 1970.
Any 1970 Firebird with rally wheels used a red PMD cap.

Seat belts were the exact same ones used in 1970 Camaros;
front seats were four parts per side;
-male lap (recoiling)
-female lap (adjustable)
-male shoulder (fixed length)
-female shoulder (adjustable)
Both female belts were the same parts, and if the car was optioned with a center console, there were clips to hold them when not in use.

Standard belts were black;
I get a little confused on belts because I know there were color matched belts, but am unsure on if color matched was optional separate from, or included with the deluxe interior option.

Good looking Formula!
Nice docs also.

The front spoiler/flares and rear spoiler only came on the TA.
(In 71 the rear spoiler was available on the Formula.)

But some (including me) put a rear spoiler on it.

Thanks guys. Window sticker options say
F70x14 white LTR fiberglass
Chrome wheel trim rings

I assume those would be the Goodyear Polyglass bias ply tires?

I prefer the red PMD caps to the ones on the car. Just made me question it, as original as this car still is.

Shame the seat belts are missing. I'm sure finding those is next to impossible.
Also has the glove box door missing. On a brown dash. Another nightmare to find I imagine

cool!!

I totally missed the original window sticker!!
(you should check out how absolutely-wrong all the reproduction window stickers are... except for ones made by a member here.)

This is what a no-wheel option, no tire option, (and) no trim ring option looks like:



I am adding YOUR pictures here for others to easily see:





That protect-o-plate has a number right under your vin which should be (if my memory serves me) the EUN (Engine Unit Number);
This is the number stamped on the top/front of the passenger side of the block - this is stamped above the 'YS' engine code - and this is a MUCH easier number to read than the partial vin down by your timing cover.

Regarding tires, I believe there were four different tire suppliers listed as being used during production (this is in at least one of the two available 1970 Firebird assembly manuals), and the precise tire your car would have received would have been 100% dependent on what was readily available when your car was going down the line.

Rally II's are a nice period 'upgrade' which most Firebird & GTO owners add;
Unless I am mistaken the same trim ring (flat style you shared a picture of) was used on both the plain 14x7" wheel and 14x7" Rally II.
Those black centered lugs are correct lug nuts too.
(Originals had plastic 'buttons' inside the front lip of the lugs (which could fall out after shrinking from age), later GM replacement were all metal, with black paint in the recess.

The glove box door probably won't be too hard to find if you're not worried about the 1970-specific door;
If you want to make your life even easier, you can get one in any colour, and paint it to match your dash.
Just be sure to get an A/C door - it should have a chromed plastic vent at the bottom of the door.

I believe that the hardest to find seat belts are the roof mounted shoulder belts, and the floor mounted male (recoiling) belt;
I believe you suggested that you have those, so you're probably won't have too hard a time finding the ones you are missing.
If you are having trouble finding some, I can double check what spares I have - it's creating complete sets from nothing that is really tough.
By the way, those black parts on your console are what the buckles connect to.

That's a great looking Formula!

Welcome to PY. Have owned several '70 Formulas with auto & AC. Last one was a silver dlx black interior VanNuys build. In back of my building have a fairly solid gold '70 350 4spd base Firebird that came with the exact same std sandalwood interior. As a long time collector/vendor/service provider, the black std belts from the gold Bird are boxed & in a Rubbermaid tub. As Jon mentions, the shoulder belts will be all faded out, very typical on Southwest cars. Can have those shoulder belts rewebbed in correct 3 panel webbing if you're interested in a complete set.

Was 72 the first year for those solid metal center caps?

1973 was the first year of the 'arrowhead' center caps.

1973-1975 used a heavy chromed pot metal cap with the exact same retainers that he PMD caps used (except they were riveted in place where as the retainers on PMD caps were screwed in place).

I believe that the caps went to a lighter stainless steel construction for 1976 or 1977.

Thanks, URJ about the EUN on the protecto plate. I'll check that out tonight. The block has the YS number on it. I gave up trying to find the partial vin by the timing cover

That is the zone and dealer code. Westward Pontiac
(the 68 and older I think had the eun and engine code on them)

[unruhjonny]

oh - ok, thanks for the correction;
Maybe it was the Canadian protect-o-plates which retained the EUN in 1970...

[Held for Ransom]

Your original steel rim, hub cap and chrome trim ring would look like second post in this thread.

Yea, that number on the block by the YS stamp is 0339139...
Whatever that means

Neat car you've picked up - congrats! It looks very original beyond the addition of the spoliers. Definitely a car you could justify investing in restoration work on.
It looks like it still even has the original open-face alternator. On an A/C car I believe it should be a 1100903. Don't let that out of your hands - it's worth a small fortune.
Nice that you got the window sticker with it as well - that's an awesome piece of documentation that is very rarely still with these cars.

[F Body Freak]

Thank you, sir. I'm quite intrigued by all the documentation of the car. That was a purchasing point for me. Car wasnt for sale yet. It just kinda found me, lol. And with the O2A build date, it's literally like 4 or 5 days older than me, which is neat. Was digging into the rotted trunk pan & window channels this evening. A little more rust there than I'd like. Hopefully, a heated pole barn will help slow the rusting down until I'm ready to tackle a restoration. It won't be out in the elements anymore. I got the car for 10K. According to what Hagerty values it at, an excellent #2 condition example is worth 46k. So that justifies putting money into a restoration

Could you post a pic of the cowl tag also?

I think 2/26/70 was the 2nd gen debut for Firebirds & Camaros? I see this car sold on 2/27. I would think O2A is a pretty early build date? Not sure when production started for the 70 cars?

They were built but not put released for sale until 2/27 I think.

Yours is definitely an early one.

I have a pic of a 01D cowl tag from Van Nuys.

It's an early enough production unit that, if you haven't already, you should check to see if it has the diecast pot metal tail panel filler piece (the piece above the rear bumper and between the tail lamps that has the license plate depression in it). The very early cars had diecast ... then Pontiac switched to fiberglass for the rest of the '70-'73 run.
