chad, turns out the goat wheels are 5x120mm, which isn't the same as the s10's 5x4.75, so i'd have to run a 2" spacer/adapter that goes from 5x4.75to5x120mm.
here is a truck i found online running the goat wheels.

looks pretty decent i'd say.
i am fimiliar with c5 wagons also, are they painted, chrome, or polished?
