I need a 7 1/4

I'm getting ready to take my 7.25 out on Sunday. Its in a 74 Duster with large bolt patern. The tubes on the 73-up 7.25 taper up from 2.5" to 3" at the ends where the backing plate bolts on. So the brakes even are interchangable with other 3" tube rears. If there is no interest in it, I think I will try to blow it up with some burnouts.
