Magnum 500 wheels for a 1971 Mach 1

[jtltoy]

I own a 1971 Mach 1 that came with Magnum 500 wheels. Unfortunately I sold them a ling time ago.
What I am wondering is what size of wheel did Ford use? I know mine were 15 inch and I believe
they were 7 inches wide (to fit a F60x15 tire). Is that correct?

15s came on the boss 351 ,standard Mach 1 had 14 x 7

Fortunately the guy that ordered it back them upgraded to 15" rims.
