I'm running BFG 235/60R14 TA's on my 66 with the original 10-spokes and there are no clearance problems with the upper ball joints. I don't know how the 10-spoke offset compares to the magnum though. Plus my fender lips were rolled during it's racing days so I don't know if that would be an issue with unmolested fenders.
