Advise on Rims/tires 67 Barracuda FB

If you want some great pictures and accompanying advice, do a search for postings by dgc333 (Dave) and you will see how his '68 notchback looks.

Would 4.125 backspacing on a 15 "crager with a 215/60/15 tire be ok on the front of a 67 barracuda. Reading posts seems to be ok but a bit of a nervous nelly when I am buying new sight unseen and spending hard earned money. Tks
