Tried doing a search but couldn't find. Planning on doing brake upgrade to disk in front. I have 14" all around now will have to go to 15. See the original 1950 were either 670x 15 or 710x 15 , with new sizes what is a good fit with out going to big. Right now my back 14's are 215x60x14, on 73 chevelle rear end/brakes. There's plenty of head room but kind of snug between brake drum and fender when taking off.
