I'm trying to find all the necessary parts to restore cooling to factory specs on my Firebird, and I can't find exact information on how air dam looks like on non-gfx 85-90 Birds.
Here's a picture of center lower air baffle for base Bird/Formula, it's shape differs from TransAm part, but I can't find any pictures, where this part is installed. Even bumper cover isn't molded for it.
Guys, if anybody can make a picture of this part installed, please, share.
Thanks!
Pretty sure that's a Trans Am part. Every Formula I've ever seen has the back edge of the front bumper curl up with stantions that attach to the impact bar. Then they have a filler on the left and right sides, with a center airdam piece that bolts to the bottom of the rad support, with a V shaped airdamn that extends across both fillers and the rad support.
GM redesigned the airdam later, and did away with the V design. The later version uses a flat piece across the rad support, and two side pieces under the fillers.
If you have a base Firebird or Formula, they actually use the same air dam and center piece as an 82 Trans Am. The only difference is, the later cars don't have ground effects that sweep up the sides of the lower front fenders. They just have a flat plastic piece that screws to the bottom of the fenders and front bumper. Here are pictures of my base 89 Firebird, the Formula has the exact same front end:
The next picture is of the center piece that bolts to the bottom of the radiator support. The middle section of the air dam screws to this. Starting from the bottom of the photo. First one is a NOS one I bought several years ago. The middle one is off my 82 Trans Am and the top one that is broken is off my 89 Firebird.
The air dam itself is all one piece. On each end it screws into a flat plastic piece that goes underneath between the fenders and the bumper (sorry don't have any pictures of that, maybe someone else does). That's all there is to it!
Hope this helps.
Edit: Found a picture on this site after a quick search:

Part 9 and 10 are used together to create a smoother "tunnel" to the rad and condenser.
#10 mounts to the bottom of the bumpercover on 85?-90 base cars and it supports the leading edge of piece #9.
If you try to just use #9 it could fold down and block airflow to the rad at speed.
I take #9 an #10 off all my formulas and have had 0 issues in the 25-30 yrs I've had them.
As Drew stated above, GM redesigned it (for simplicity/less parts?) on the 91-2 cars.
So, on 85-90 Formulas, part #10 on one side simply bolted to the bottom of bumper cover, which has no molded "gaps" on it? (My bumper cover is flat in the middle, where this baffle should be)
dug this old thread up my question is related I have a 90 that I am planning on upgrading to 91-92 type does anyone have a breakdown of the parts (like in post#4) the newer style front end takes or are they same or?
