I assume by your handle and the fact that they're 8 lug drums that you're talking about a '52 3/4 ton.
AFAIK, there aren't any 3/4 ton Huck to Disc kits. Anyone who has done it has fabbed their own stuff from parts off of another truck (or trucks).
Though, if the rear drums are in any kind of shape, I might be convinced to buy them off of you.
