I've got a 91 Max and i was wondering if any other light would fit in the rear. I'm hoping to paint my car and smooth out the back pannel and paint inbetween the lights. Any ideas?

 

anything will fit with enough fabrication. Its all in how much you want to spend.

The only lights that will directly bolt on will be 89-94 Maxima tail lights.

The 89-91 lights are different than the 92-94 and the SE tails are different than the GXE tails also in each set.

 

IF you want a rear clean shaven look. I probubly won't get to do it myself but.
Take some skyline r34 tail lights. And remove the housing, then french them in. Thats what i would do if I didn't do wrx tails.
