I have a question i seen a 91 firebird with a 85 transam front clip on it and i was wondering is it a direct bolt on or does it req. mod.? and what about the parking lights etc.... thanks

 

The holes for the bolts for the 91-92 front ground effects will be in a different location. The inner headlight housings are different. The impact absorbers are different. The 85-90 ground effects for the front of the fenders go up a little bit further than the 91's. An 84 trans am front clip with ground effects would probably flow better with the 91 ground effects but you couldn't have foglights...(thats a matter of opinion though, still would work fine with 85-90 front clip) Wiring would be the same on the parklights.

In other words, it requires a little modification

 

this is what im talking about im not buying the car but just an example of the 85 bumber on the 91 firebird...
