G'Day Craig,
All depending on what diff you're running and what size its been cut down too, if you kept it long you'd need something like a 5 stud Magna or AU Falcon rim offset wise, if you made it same sort of width as Escort then anything from the X and E range Falcons should fit. I'm unsure about B series?
I've got 15" rims from an X series Falcon. That is using UPC brake/hub conversion on front and a shortened diff.
