I had a wheel off of my wife's 99 Silverado truck (2
wheel drive half ton), because it had a flat
yesterday! The bolt pattern is the same as the ole
trucks use. The offset is about 1.25" negative
(wheel mounting surface is towards the outer part of
the wheel). The center hole is only 3.06" diamter,
so it won't fit on an early hub which needs a 3.5"
hole. The lug nut holes are big, and the old 7/16"
nuts will not work...and the correct nuts have a big
14mm metric thread.
Hope this info helps someone...
