Im not sure if youre still looking for a MC2 B-4, but I was looking for a B-9 and B-10 and called Forge-Tec who bought out MC2 and spoke with Anthony, and they have certain wheels from mc2 left. I to wanted the fifth wheel for my sut spare carrier, and was able to get them. They wouldnt sell it directly to me though, only a dealer. So I went to a freind at a local dodge dealer and they orderd them, should be in next week.
However how the hell do you mount it two the carrier with that damn half circle sticking out? I would imagine cutting it off???? Or do they make some type of adapter or kit??? Since there is not an opening on the wheel like there is on the stock tire???
