Rick,

I bought an older car too..... never had to replace rotors.... yet!

Anyway, from the book that came with my car there are several cryptic notes and the below one refers to the rotors:

Rotors, '70 Monte Carlo.
take out spacer
machine off .090" on flat side
machine off .090" off nut

I don't have a clue as to what that means, but seems that the rotors have to be machined a little to make them fit.

If you have still have the old rotors, look over them real close and see if you can find what was done to them, as you compare them with the new ones.

Let me know that you find, as one day I'll probably be in your situation.....
