74 Dart/Valiant - Couple ?

I was wondering if anyone knew what the bolt pattern on the wheels would have been on a 74 4-door Valiant/dart with a 318, disk brakes and AC.
Also what rear end would it most likely have?

May be a profound questions but I was trying to save a long trip and I cant get an answer from the guy who has it.

Thanks,

Mop
