The early disk brake type 3s (66-71) use a smaller caliper. The later years (last month of 71-73) use a larger caliper that originally came with dual bleeder valves. Replacement late calipers now have only one bleed valve, I believe. The early and late calipers have completely different bolt mounting patterns: different size bolts, different spacing. You can't switch without changing lots of other things. Both calipers have 42mm pistons, so the braking action is the same for both. The late caliper uses a larger pad which gives longer wear and may give slightly more resistance to fade, but I think in reality it's hard to drive these cars to the point of brake fade anyway. If you have a problem with fade, it is most likely that you have one or more caliper pistons frozen in place and your calipers need to be rebuilt.
