What year Shaker Hoods are the same?
 

Could someone provide info on which years are the same for Trans Ams?

Shakers"

Shaker Hoods?

Front Fenders?

I am more concerned with correct appearance from the outside and not all of the nuances of webbing or small details under the hood.

Thanks,


PS I tried searching, but was unable to find the answers I needed.

Shakers - 70-76 (73-76 mount with a ring clamp to the base).

Shaker Hoods - 70-76

Front Fenders - 70-81

70-73
Externally... the hood and fenders are identical.

70 shaker is slightly thinner on the rear opening edge.

70-76 fit the rounder front ends and the 77-81's fit the flat hood models.
SHAKERS:70-76. 70-72 mount with studs to the aircleaner, 73-76 mount with rings like stated.
HOODS:70-76, just bracing that you are not concerned with.
FENDERS:70-81,just bracing and mount differences.
main difference is 77-81 hoods and scoops are a beast of their own. all non turbo hoods are the same as far as i know. there was talk but not sure they confirmed a difference in some later small block chevy 305 engine TA hoods.
there is a 77 early 78 pontiac scoop which is about 3/4 inch shorter in height, a later 78 pontiac scoop, a 403 olds scoop, a 305 chevy scoop.
think that is all, but always willing to learn.
