disk brake options (factory) 73 Scamp

Thank you for the info. I at least have an angle to take now. I've been out of the mopar scene for quite a few years now. I do have a 79 Volare front end under a 50 that I have been tinkering with for a few years. I don't suppose that these parts will fit either?

The '79 Volare parts will fit. The FMJ spindles can be swapped over, and everything from there out will work. That would also give you the 5x4.5" pattern.
