PROLSC. I may be able to save you some grief here. Are you converting your 65 to disc brakes.I've been going through the same thing with my 64. I was told that going the 69-70 spindle route was not the way to go because the rotors were very,very expensive. Just before sending you this I called Advance and Autozone and neither carry a listing on a new rotor,Which leads me to believe the person that told me that just may know what he's talking about. You can buy the whole kit which is a little pricey.and I didn't want to go that routeand proberly wont.You can buy the adapter and use the sindles that you have. Look in any Super Chevy Mag. and you will find a dozen adds for disc brake conversion. Engineered Components Inc. advertises the basis bracket kit for $110.00. Make sure that any kit that You might buy will work with the size rotors and calipers that you want to use. Hope this is useful .If not have a great New Year anyway.
