I ran the stock ten holes on my 86 with 87+ spindles, rotors and calipers with no clearance problems. I then put cobra R's on and put the wilwood kit on the back, doing the master cylinder/PV upgrade now and trying to go with stainless -3an lines. not easy and I think that there are only a few combinations that will work for us, I am finding out about a cobra MC tomorrow. I know that the SVO is probably the best bet for fitment but I like the look of the 94-95 MC with the stainless lines. Up to 86 they were SAE fittings on the MC, 87 and later were 10mm and 12mm.
