Thanks, Southtowns27 you probably saved me a bunch of work, and probably talked sc4x4 out of doing too.

Although if I had the whole truck I'd probably cut the frames and splice them together. I know - fire up the torches boys and let the flaming begin! But before you get to carried away about it being unsafe and all, it CAN be done safely.

I think your gears would fit, although it's better to let somebody with experience do it if you can't. What are you going to do with that dually, if you don't make the swap?
