I'm looking at purchasing a BBP 7 1/4 rear assembly (brakes and all) for $50 (see parts for sale section). I want to put it on my 71 Dart swinger 2 door when I go to discs up front.
I don't have the car with me right now (getting it moved down here in August) so I can't pull out the measuring tape and make sure the track and spring perches are the same width. How much of a hassle would any fitment issues cause and would it be worth it for the cost of the assembly? The owner has said he's not sure what the 7 1/4 came off of.
In summary- should I just buy the thing and deal with fitment or could it cause me massive headaches and/or premature hair loss?

Thanks, Josh

It's not rocket science, we're just splitting atoms.

Not much else fits an Abody, so it's much better to start with the proper rear end. Get some measurements from him, and someone with a car handy will be able to double check if it's the right widths for you.

Actually tech archives on Moparts has the widths. I am wondering if it has 10" brakes. I'll check in the AM.

thanks for the link. Haven't seen that before and it is very informative.

An A body BBP 7-1/4 will have 10" brakes. .
