If I read his request correctly he wants to keep his SIX lug wheels. The Chevy Colorado/GMC Canyon have the six bolt pattern and are close in width wise but I don't know if they are disc or drum. Most of the Jap trucks except Toyota 2wd are six lug and some with auto trans have at least a 2.73 and maybe shallower rear. Spacers probably required. The S10 4wd rear is what the S10 frame swap kits recommend for a 47-54 but on a 52 we did that kept they wanted to keep the six bolt pattern we still used long lug bolts and a 1" spacer to give a better tire to bed clearence. Google "six lug rear end dimensions" and see what comes up. If you're in a junkyard, can count to six, and own a tape measure you're two steps up on the ones of us posting answers.
