91-94 swap for 89-90

are the 2 front ends direct bolt ons? or is there modification needed? cause i really don't like the 89-90 front end and i may be able to get a 91-94 front pretty easily.  thanks for the help

yeah its just a different front bumper, everything else is the same (lights, fenders, hood and what not). you shouldnt have any problem putting on an aftermarket front bumper, or just one from the 91-94. just pull off the old one and slap the new one on
