What are your existing wheels that you want to continue to use? I’ve never found an answer as to whether or not factory pre-1971 16, 16.5 or 17” wheels clear the caliper on a 73+ factory disk setup. I’m particularly interested in the 17” question - and wanted to ask what your wheels are. If aftermarket, you’re fine. If 66 original - I don’t know for certain they we’ll fit (clear the caliper). In the 15” world, they will not - but this is the 16 or larger world, and I don’t know if the taper on the backside of one of those wheels clears a caliper. Seems like it would come closer to clearing it at least. Anyone know?
