Stupid question...

Does 4860 mean 48mm top diameter, 60mm bottom? Just wondering because I'm considering getting a set of HPMguy triples, and it looks like he's doing a run of both 50s and 4860s. I prefer the 50s and have a line on some , however the 4860s are much more common and modern. So my crazy brain is thinking, why not get a 4860 bottom clamp and a 50 top clamp, machine up a 5mm aluminum collar for the 50s to fit the bottom clamp, and if I ever get a set of 4860s, I can simply use a 1mm shim on the top clamp. Feel free to tell me I'm a crazy idiot , but at least assuage my ignorance in the matter .
