Does the 91 front bumper bolts up to a 90 easy?

 

im pretty sure the differences are only cosmetic...it should fit fine...but im not 100% sure, so wait for someone who is...or just try it...

 

I'm trying to swap the bumper too

 

It fits fine but it sticks out a little farther than the fender so you have to get the fender extension things that are on the bottom of the fender on the 91+ car if you want it to look flush but besides that everything fits fine
