Guess that makes sense - in so far as it sharing the YR code with Federal.
Odd that the 4bbl XE had to have its own engine code and required 616.
Just the way they did it - but odd

I never realized this before, that the 3x2 Auto Cali cars all got a free pass on AIR.
Never paid real attention to the deal

Looking into my files ... i think i have a copy of the BHC for your 66 YR 3.90 car .
Dealer code 23-107 ,, paint code P2
and a whole lotta options !

That was a good idea / thought on the speedo adapter John.
with 3.90 or 4.33 axle

Apparently only the Automatics needed it though (?)
It is code 591 (speedo adapter)
TwoJokars 3.90 Automatic has it on the BHC (591)

Also worth making mention
That car was 3.90 with "FO" WIDE RATIO 4 spd .
Not "FT" Close Ratio

In 64-65-66 you could get the WideRatio M20 with a 3.90 Axle - if you knew the order form and knew what you really wanted.
M21 was by default with 3.90

I don't know that it was possible with 4.33 Axle in 66 (probably not)
My 65 WS was built 3.90 with M20

Sorta cool stuff when you find it out and see supporting documents.

Do you have any history or more info on it? Just curious how you got it. I got it from PHS back in 2012

I'm not 100% positive - but maybe you posted it on here in the past.
Also have a copy of Reproduction Window Sticker for the car.
Otherwise maybe from eBay or Website before you bought it. idunno

Seems like there was a thread some years back about 64-65-66 Automatic GTO's with 3.90 Axles .
Not even a full handful were known or documented.
VERY VERY Rare Combo GTO's
Believe in that discussion is where the documents were posted.


E D I T
by "files" - i meant computer picture files - saved on computer.
I don't have a paper/hard copy of your documents.

[johnta1]

The 'J' after the YR is for Automatic.
The 'P' is for 3.90 gear ZK

Also I made a mistake for the metallic brake suggestion. It would have to be ordered with the gear to get it. (same for this 3.90, eligible for metallic brakes)


Yours having the '3' would coincide with the speedo adapter also?

[Baron Von Zeppelin]

John must have me on his ignore list .

The 3 in 73-3 has nothing to do with a speedo adapter.
Its the Special Order Axle Assembly

The speedo adapter has its own code by itself = 591
And there is a charge for them

The 2 WS cars posted with 73-3 (P 3.90 and S 4.33) do not have 591 on their BHC's
no speedo adapters

The 3 on their P-o-P's is in conjunction with their special order axle assembly 3P & 3S

[johnta1]

Naw, just speed read through most of this while reading my notes.

That was a good idea / thought on the speedo adapter John.
with 3.90 or 4.33 axle

I thought the 4 speed would get it also, just a different style/gear adapter?

Edit: Still not reading well.
I saw where the speedo adapter had that code. Didn't know where it was on the buildsheet though.
Sheet I saw had a space for speedo gear, and another separate space for adapter.

[Baron Von Zeppelin]

What i was saying to you was -
that was a good thought just pulling it from the dark with no data to go by.

But i laid it out with the proof and pudding what all that actually was.


Only the Automatics required it
And it was its own code with a charge of $11.06
Code 591 will show up on the BHC if it had one.
The WS cars do not have 591 - so the 3 on these P-o-P's can not relate to a speedo adapter.
Or else Dan's WS /4.33 car would have 591 on the BHC

The 3 on these P-o-P's is for their Special Order Axle


The 66 421 Bonnie P-o-P has a 1 for its standard Posi

[Baron Von Zeppelin]

Sheet I saw had a space for speedo gear, and another separate space for adapter.

okay i see your problem - i think

Look up in the Box 59 and read the contents listed
59-1 is speedo adapter
Box 59 is Blank = NO speedo adapter

You are looking at the lower boxes where it provides for the gear , and for the adapter if required.
XX means non-content in that adapter box.


-------------------------------------

Trying NOT to confuse this subject
Jokars car is an Automatic with 3.90
His car DOES have 591 on the BHC , and a charge for it on the window sticker
But it is NOT the definition for the 3 on his P-o-P
the speedo adapter only coincides because he has an Automatic

[Baron Von Zeppelin]

XX means non-content in that adapter box.

The Buildsheet Car had NO power steering (501 / 50-1)
The power steering belt box lists XX = non-content
Just like the speedo adapter box = XX = non-content

Yup, not much thought given to the silly two-speed automatics from back in the day.

When they were coupled with a Tri-Power (YR) in ‘66 and being sold new in California having the (614) option makes for a scarce build. Never a Smog (A.I.R.) on these cars.

My buddy Anstein (I hope I spelled your name correctly) from Norway has a really neat YR GTO.

His car along with my YR when using the PHS/CBH information and the POP answered all the above questions long ago.

Engine, transmission, rear gears and speedo adapter, etc.

Everything falls into place with the codes.

The last four pics pertain to my YR.
Transmission code NA 060 = GTO, 60 days into the build year.

The production month code (H for January) helps confirm the table below. I think there are many option codes that will need to be confirmed moving forward, but we now have a few figured out.

GREAT picture of the Transmission Unit Number
It shook my memory and now i recall seeing it disclosed on here before - perhaps by you with the same picture .
You're the Mr. YR Man !

With that NA 090 presuming 090 to be sort of date figure -
that would lead a lot of various T300 cars to having the same duplicate TUN on their P-o-P . Interesting

What do you "think-or-know" the second 4 applies to on your P-o-P ?
We seem to know pretty certain one of them is for the 614 option/system.
I looked at the possibility of it maybe being for 454 Rally One wheels - But - Jokars 66 Fremont YR also came with Rally Ones
and his P-o-P doesn't have the second 4 stamped on it.
Or he hasn't mentioned it here , yet

I am guilty of not following the T300 GTO's very closely
The ones with 3.90 gears grab my attention though, just by the total uncommon'ness
i still have a 66 Blk/Blk Hdtp YR 3.23 car

[Twojokars]

Hi Chris, name spelled correctly and as you said there was a thread some years ago where much of this info was discuessed. And by the way i checked the painting on the brake drums as we talked about earlier and under the black outer layer there is red paint under, at least on the rear ones havent checked the fronts

Here is a couple of pics of my P.O.P and as you see it the condition is kind of rough i guess its been laying in the glove compartment for all those years it was stored in a garage and get moist and rusted a little. I have kleened it a bit so i can read everything on it. Still in the service booklet.

Baron, as you see the number 4 is also on my plate so that could well be the rallyes as you maybe tought.

I cant check the number on the trans cause i dont have it. I did find it about 3 years after i bought the car and i buyed it and ordered shipping. Itwas ready to being shipped overseas to me when the shop lost it. I could get a replacement correct 66 ST 300 that they had but the shipping cost was so high, and since it wasnt the original for the car i let it go. I have a 350 in it

Here is my 1966 YR.

EXCELLENT !
EXCELLENT !

Thank you for providing so much useful data from your GTO

btw , there was only 1 other 66 YR 3.90 car mentioned in the ST300 / 3.90 thread.
And it might have even been your car while it was still with the original owner.
Do you recall the story/account given about it ?
I can't remember which PY member it was who knew the car and told of it.
He had spotted it back in the 80's and inquired about it.
And seems like it took place in california

Regardless, yours is a double-rarity with YR 614 and YR 3.90 Axle

Good Gracious Kenth !
I knew you had that Export/594 YR 3.55 MetallicBrake car
but have never seen a picture of it before.
It is Stunning

My uncle (by marriage) got a 66 Lemans same color and hubcaps as yours new from his parents as a college graduation gift.
He kept it for a long time and i rode in it many many times as a youngster.
That was a tremendous FlashBack
Thanks

[Twojokars]

Baron, i think Chris had a story about it and i am almost 100% sure it is my car he found back then. Maybe he will chime in on the story

Kenth, knallfin bil ser jo ut som den kommer rett fra fabriken
