IIRC from when I measured on in the shop, they come out to right at 63", give or take. They do have a 6x5.5 bolt pattern. You might want to consider the 10 bolt from a 4x4 S10 with the ZR2 package, '98-'04. Those are basically a narrowed version of the full size truck 10 bolt, only with the 5x4.75 bolt pattern. They also have factory rear disk brakes, and usually a factory gov-lok system.
