Drill, Tim has it right, just use wheels off a 2001. I haven't located a set yet for my 95, but they appear to be the best solution to bigger tires.
I've got a set of spacers my neighbor machinest made for my truck on the shelf in the shop. We made them a couple of years ago and I never followed up with the install due to concerns about shearing the necessary longer wheel studs. My original idea was to replace the stock studs with longer ones to allow for the spacers (didn't want to drill 8 more holes for a second set of shorter studs in the spacers, (that's the way big trucks do it) due to limited space on the spacers).
If you have a set made, be sure to mill the spacers for the locating step on the axle. Our wheels center on the axle and not the wheel studs.
