78-81 Pontiac Motor Mount Brackets
Is there a diference between Late F-Body 3-bolt Pontiac Motor mount Brackets 75-81 and the Brackets used on 78-81 Pontiac 301 a & G Bodies?
I ask as a freind is putting a 400 Pontiac in his 83 Bonneville G Wagon. And I have a set of brackets that are either from a 79 301 powered Firebird, or a 301 Powered 1980 GP. I didn't seem to tag them and now 10 years later can't remember.

The g body brackets are different. They should have part numbers stamped into them. The pic is the mounts from my '80 Lemans 301.

time for repro?
recently saw a set of the bird shells for sale on ebay for $100. they were just cleaned up & painted. 2 me this is ridiculous ! isn't it about time for somebody 2 make a repro? there's not much 2 em, so a cheap chinese repro should be a good seller with a reasonable price. or maybe somebody already has em & i'm the last 2 know. do ya'll know of any?

The Fbody one will work but raise the engine higher which is not good since Gbodies are hood clearance limited already.
The Fbody ones have an F stamped on them also. Give me a reminder in a week or 2, I my have a extra set of Gbody ones. Moving my shop now and can't find a damn thing!!!

I would be interested in a set. I am putting a stroker 400 in a 1986 Grand Prix 2+2.

The F-body and big car ones also make your header situation worse. They appear to be just like the 78-81 G-body mounts until they are side by side. Then you can see the difference. I have a set of Indian Adventures mounts that will allow the use of an early or late block. I need to draw them up in CAD so I could get a few made.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
