You need a SIX LUG axle to fit the original wheels. If your new wheels aren't six-lug...you'll have to figure out something else.
You're looking for a 14-bolt rear cover. Any 14-bolt cover, with six-lug wheels is going to be a 9.5 semi-float. A 10.5 will be a full-float, and it'll have eight lugs.
You'll need an axle from an '88--'98 4WD truck, the 2WD axles are the wrong width. GET THE MOUNTING HARDWARE WITH THE AXLE. The U-bolts will probably have to be new, the mounting plates are bigger on the 14-bolt than the 10-bolt. As said, front and rear gear ratios have to be the same. Either match the front, or change both. Changing gear ratio also means adjusting your speedometer, and maybe the programming of the computer.
The rear brakes on the 14-bolt rear axles are bigger and better.
You'll have to have one conversion U-joint to get the rear of the driveshaft attached to the axle. I forget the number.
The driveshaft fit as-is on my truck, but I didn't have a lift kit installed. With standard-ride-height, the driveshaft pushes into the trans about half-an-inch more, so I had to polish the yoke to remove accumulated dirt and rust. With a lift kit, i suppose it'll pull out of the trans overall, but "I guess" 1/2 inch less than it would with the original axle and a lift.
