So I've upgraded my 1970 914-4 front suspension with the turbo tie rods, 1973 struts, ball joints and rotors (with centering disk). And now I need help deciding on calipers. I have a set of the original 1970 calipers that were rebuilt and only have 50 miles on them. The problem is, one of them has been modified with a grinder to fit the 1973 strut. Seems to work OK, and the other one is still original. My first thought was to grind the other one down, using the first as a template. Or I could try to find '73 style rotors (rebuilt). The BMW i320 calipers is another option, but they would need to be ground down according to the other postings. Also, any thoughts on the potential crude grinding method versus machining? I appreciate any feedback
