im buying a 88 rx7..but what do i have to do to put on a 89-91 front bumper on it?? do i have to change hood and fenders or just the front bumper.....2nd question..long time ago i had a 88 turbo 2 but i tried to put in a 91 gauge cluster in it and it didnt work whats up with that??

 

bumper should bolt right up. guage clusters arent the same so they wouldnt swap
