Hey guys, I am upgrading my 70 GS ragtop from power drum breaks to disc front, and bigger drums in the rear. My understanding is that I an going to have to change from my stock 14 inch rims to at least a 15 with a 3.5 inch offset to handle the disc. What size tires and rims will it handle before I have to do any modifying. (I'm looking for a range) to keep as a good driver.
