small bolt pattern Cragar s/s

Awesome guys on the rim help!

So I have a 64 Dart, has an 8 3/4 rear. I have it mounted on the stock pads, what size cn I fit under the car? In the old days an E-60-14 would just make it and I had the lip bent up a little for more clearnace.

I was thinking a 14x7 with a 215-60 in the rear and mabye a 14x6 with a 205-60 in front?

Or should I go with around the same size in 15"s?
Looking at a 215-60 or a 225-60 on the 15 is a little taller. And a 225 -60 is about 1/2" wider than a 215-60.

Also what about front disc brake clearnaces? What offset etc is needed?

Any input here would really help!

P225/60R15 BFG T/A Radial,Overall Diameter 25.6", Cross Section 9.0"

Kind of like this size for the height and seems rear width would be decent and should fit? It is a little taller yet the width get me a little more room.
