does he just need different brackets? if so how much are those?
The 3rd gen bumper brackets mounted to the side of the frame, not the front of the front x-member as on the 2nd gens.
Smittybuilt wont have bracket for him to use, but he should be able to make something using the '94 oem brackets.
The 3rd gens are also wider than the 2nd gens so it may not look right even if you fab up something to mount it.
If you don't have access to a welder/aren't into fab work, the easiest/simplest thing to make would be an "L" bracket out of some 1/4" steel plate. You would bolt it to the bumper and then to the stock mounts on the '94. I make something similar to this when building one of my bumpers(designed for 3rd gens) for a 2nd gen, it allows me to use one design/mounting system.
