I found them in a NPD Camero Catalog, they are called Firewall to floorpan brackets, The tech there told me they were not for the firebird but they look just like mine, He told me the firebird never had them, Which is funny because Ron (the guy welding the sheet metal) has a 67 and 68 convertible untouched and they are not there. He's had the 68 since he was 16 it was his dads and he's 56 now.
Another Firebird mystery
My convertible has those as well, my coupe doesn't. Why would Fisher body produce the Camaro with these and not the Firebird. Both cousin cars rolled of the same assembly line. It would have been more costly to make different versions between GM divisions.
The debate over the '67-8 convertibles having these is evedent in the pictures posted. The guy doing the welding on your car, I bet his memory is a little rusty... pun intended.
Zak, the person you spoke with at NPD isn't a 'tech'. He's a phone jockey that may or may not have a background in the automotive trades. If he does, he probably doesn't own a vintage car or know much about them.
Personally I have had a few transactions with NPD where I was given bad information resulting in returning several part orders. I now only use them if they're the only supplier of a part I need.
Ames has these floor/firewall extensions to @ $49.00. And they know what they're talkin' about. If the sales person doesn't own the particular (model & year) car your ordering parts for, he'll ask someone who does. Ames has been very helpful when I needed questions answered.
