1977 GP Exhaust Manifold
Hi To all. This is my first post.
I have an ultra clean '77 GP (400 cid), and the LHS exhaust manifold is cracked. I believe the GM part number is 499623.
1. Are the 1977 400 CID Firebird exhaust manifolds the same as the GP ?
2. Where can I purchase a (preferably new) exhaust manifold ?
3. Has anybody had any luck welding an exhaust manifold ?
Thanks,
M....
