Well, since nobody's helping out here, maybe I can at least give you some info. I can't address your specific circumstances, but I can tell you what I've got under my '72. Now, I'm running 15 inch rims, rather than 14s, but I can tell you that 15/50/235s on 7" rims fit just fine up front. In the back I've got some 15/60/235 Mickey Thompson drag radials, also on 7" rims. This setup gives me a slight nose-down rake that looks thoroughly badass. Anyway, hope you can get something useful out of that...
