Anybody know if stock coined dually rims will fit/work on a dually disk brake dana 80?

 

I can't speak from actually trying it; but, I am going to speculate NO, on account of no provision being made on the mounting surface to accomodate the "coins".

When a friend swapped his 70 for an 80, I do know that he had to end up getting the rims that were on the 80, as his old rims would not fit; why I do not know.

 

Will 2nd or 3rd gen dually wheels fit on the front axle?

 

The 2nd and third gen wheels will fit on the first gen, but the 1st gens will not fit the 2nd and third. The center hole is too small on first gen wheels.
