Are you kidding, you're killing me here. Saying its a 95 Z71 tells me only what option package and a year, its like saying it is a red truck. It tells me nothing about the truck to tell what axle it is. I mean is it a pick up; 1/2 ton, 3/4 ton, 1 ton, Suburban, Tahoe, all of these were offered with a Z71 package and have different axles. Tell us something so we know what axle you're talking about.
With 33" tires 3/4 ton and 1 ton would be way overkill. Not to mention no matter what axle since it is a GM the lug pattern will not be the same as your front Jeep CJ bolt pattern.
