Can anyone tell me if there is a difference in the the rear brake drum, backing plate, and rear wheel cylinder on a 67 vista cruiser, as opposed to a cutlass or a 442?

 

I bet the Vista Cruiser would have larger drums. I am not sure though.

 

The Vista has wider rear drums than a Cultass, same width as a front drum Cutlass, and the backing plates are different to accomodate this and the wheel cylinders are left and right with the bleeders facing 45 degrees rearward...I put Vista rear brakes on my 442 convert...and then I just recently read here that we can install 11 inch suff from a '76/'77 Cutlass...aaarrrggg
