i bought a 75 firebird and i took off the whole front clip to paint the engine. i took off the radiator core support only to find out that its rotted real bad. anyone know where i can find a new one?

New ones don't really exist & 85% of used ones are rotten under the battery like yours.

I'd check your local classifieds like Craigslist, or the parts for sale sections here are PY, Trans Am Country, Firebird Nation, or Bandit's T/A forum. You're bound to locate one sooner or later- they're out there.

As a plan "B"; is there a local fabricator that could repair yours properly?

I did the same thing, My holes for the mounts were rusted to the size of the rubber
bushing, I took a rough measurement as best I could to relocate the holes later,
I cut the opening into a square back to solid metal with a dremel tool and a cut off wheel, I used a piece of scrap steel the same gauge/thickness and made 2 patches
that fit the opening as close as possible, then I had the welded in by a welding shop.
Once I had solid metal I located the new holes with the measurements I took before
cutting. You can use a Hole saw in a drill to make the new holes.

If you can do most of the fab work & cutting, a welding shop or Body shop wont
charge as much for the work.

If the whole support is really rusty and thin in spots, it would be better to
replace it with a better one, I think the more easy to find 79-81 supports will
work on a 75 but It sits on top of the frame rails instead of bolting Thru/Under
like a 75 does. It will take some shimming for a 79-81 support to work correctly.

I know the 1974-1976 supports I had were all the same part.

I think 77-78 used the same support as a 74-76 but I never had a parts
car 77-78 to know for sure.

79-81 Uses the support that sits on top of the frame rails
I used a 79 support on a 75 and it worked but was a pain
to make the front end line back up.

I also never had a 70-73 support to know what is different, I know they cost ALOT
to buy.

I wish they made a repo support also
Good Luck with your 75!

I replaced the radiator support on my '72 over 18 years ago- I think I used a later model unit as I thought they were interchangable from 70-81. I didn't modify it, but it's still on the car now and seems to fit well.

To bad you dont live near me.
Can have mine for free.
You just have to go get it back from the guy who borrowed it 2 yrs ago so he could move his car
And while your at it, get the shifter he owes me since last August.
