hello, long since my last visit...


years ago, i've bought a Lower Under Column Cover Panel (Gm part 10013085) i wonder on what firebird year model this part was installed? all info that i've found is 77 -81. i guess it could have been installed on manual trans.



anyone know more about it?

thanks

I have that cover on my 1979 TATA. I also removed one from a 52K mile '78 parts car. I haven't seen one on any cars earlier than '78, but I am sure many people removed them and just tossed them instead of reinstalling. I should look at the one I took off the '78 and see if it has only one pedal slot instead of two. That car was an automatic.

ok, and the cars you've seen with this part was AC or not?

i have it on my 79
it was an AC car too

It should have insulation on the back. I have always heard them referred to as a "hush panel". I believe they were part of the sound deadening/insulation package

That's correct

Have had that cover w insulation backing on all of our '78 (both manual & auto) & '79 TA's w A/C & factory "custom" interior option.

One reason they are often tossed: They can be a real pain as sometimes dropping down and limiting proper pedal travel & operation. Ex: Brake pedal hanging up on insulation or ABS plastic cover edge.

Although I still have them installed on our current '78 & 9s - Even with "adjustment" of the two mounting screws etc. the cover can come loose and move around...

Your results may vary!"

so, for sure, it only cames on 78-81. maybe 77?

That panel is a pain in the arse! I couldn't remove mine and throw it in the trash fast enough. It is amusing that they could build a car that rattles like a 79 T/A, then be concerned
enough about noise to install a "hush" panel ! Hello McFly! If they wanted to install a hush panel, they should have put one on the t-tops!

Most favored in old Barn cars, by mice from coast to coast.

My take.....78-81....Custom Trim option with AC....

If your T-tops rattle......your latches need adjustment.....weather seals need replacement OR the roof tab mount bushings need to be be replaced.....
