You would need a complete assembly including the lamps, impact bar, all brackets, the absorber, retainers and the associated parts.

It will bolt up but will be a pain to make it look correct. All the inner workings that seal off to the original cover will not mate up to the later version. I have done this before and if you are looking for an OEM type look you will be changing and fabing a few parts. Just my .02

You have it easy will bolt right up, doing a 91-96 bumper upgrade on a 90 vette. Much harder not a simple bolt on with earlier ones 84-87, you need some custom made adaptors to secure the airdam spoilers. (bumper to the plastic splash guards) have been there and done that..

To clarify; my experience is based upon the older 84-87 car. Hope this helps.

The front splashguards (in front of the front wheel under the overflow container r/h side and vacuum canister l/h side) are different in the 84-87 corvettes, the 91-96 front bumper has a different arc in where the side air dam /spoilers bolt on (and is a bit further to the front of the car). The adaptor is needed in 84-87 vettes to fit the later style front bumpers, see the pic below (crappy phone pic but you see the adaptor required with arrow pointed to it the original 84-87 splash sheilds sit higher). 88 onwards you don't need this adaptor.

The rear bumpers and wide moldings etc are an easy bolt on. The 91-96 front bumper fits fine on my 85 otherwise!!!!
