How about thin dash gauge bezels ?

[bird72]

What is different on the roof drip moldings?

[2manyT/A'S]

I'm getting a bit rusty on this stuff,but as I recall,

- waterpump pulleys are specific to 70 Firebird V8 (both A/C & non)

-Also power steering pump? (one year in second gen.anyways)

-power brake proportioning valves,brackets,lines,etc. (one year in second gen only)

The thin dash bezel rings (and accomodating dash bezel) were used through '72.

[tajunkman]

Last year for high compression

Blue trunk release button ?? 70 only ??

Different Firebird fender script.

Early inside A pillar moldings have that extra screw hole.

Black center PMD caps.

70s are the coolest Good thread.

70s are different. Coolest? There are pluses and minuses....but then I'm partial to 71s!

[Dens71TA]

Stainless side window weatherstrip channel
Trunk floor different above rear axle for EES clearance.

[giles]

Substituting plastic for steel plug wire standoffs
removing the sunvisor center tabs
outboard front seat belts (retractors in 70, flat in 71)
eliminating the chrome engine dress for 71

[2manyT/A'S]

ONLY year for code 10 Polar White (69 + 71 - 81 are code 11 Cameo White)

[blue71ta]

Angle cut on chrome exhaust tips is '70 only

Radiator support is different than '71/'72, correct?

Oops! Core support was already mentioned.

Another one is the manual trans shift knobs (black ball for standard interior, red insert w/shift pattern for deluxe interior/4 spd and red insert w/arrowhead for 3 spd)

big matt: I believe that started in late '72 and went into the '73 model year...

If I new that the 70 bird was so special I woundn't have bought one! I think that photos of these parts would be benificial for all firebird owners.

OK... if we're going to throw colors into the mix, you have to also mention the eye-popping psychedelic bright blue interior option. Just like the white paint going from polar to cameo in '71, the blue interior was toned WAY down. If you see a nicely restored white/blue '70 sitting next to an equally correct white/blue '71, the '71 has this sort of "hey... who turned off the christmas lights" look! The red '70 interior was much brighter than in '71, too.

Overall, the list looks pretty full. Not much else I can think of other than:
1) '70 woodgrain instrument cluster bezel had a lighter woodgrain tone than '71+
2) Through about the middle of the '70 model year, the trunk floor had 4 ecoat drain holes (later cars all have only 2).
3) Not sure I saw the chrome gauge ring bezels for T/As mentioned. I know some early '71s got them as well, and many '70s seem to have not got them, but this is still mostly a "70 thing".
4) '70 rear quarter side trim pieces had no ash trays.... did '71s have ash trays?
5) And for some reason I was thinking the rear seat back frame was a bit different on a '70, too?

Don't the 71 and up cars have a seat belt light in the dash as to where the 70's do not? That might be another one but I am not near my car to look.

160 speedo with seat belt warning was required for cars produced 1/1/72 & later. A few late Dec of '71 car were prob built with seat belt warning light as well.

Have examined original '70 1/2 T/A's with two different sized rear swaybars.
All the original & complete '71 & '72 T/A's I've ever looked at def had the 7/8" rear swaybar.

['ol Pinion head]

Whats the deal with a blue trunk release button?
I've only examined green ones in 2nd gens up till the changeover in mid '74 (yellow).
