Maybe I will take a different approach. Does anyone know of a hub style spindle that is a suitable replacement for the Wilwood Pro Spindle. I looked through a couple Mustang II / Pinto forums looking to see if there was anyone doing a similar swap to see what produce was out there, but I didn't see anything. So far it appears to me that if you want to upgrade from the Mustang II, you are cutting everything out and replacing.
