I know that '65 was the last year for the smaller body A-bodies but i don't think that the fenderwells are that much smaller. i think that if you want to fit a 10" wheel in the rear with the least headache and downtime, you just need to take some very careful measurements and get a wheel with the perfect backspacing. That's what I did and it worked perfectly. I have just about 1/4" of space on either side of the tire sidewall and the tire sits about 2" up in the fenderwell. If you decide to go this route i suggest that you either buy or try to borrow a Percy's Wheel-Rite tool. It will allow you to simulate your desired wheel and tire combo and check for interference. Once you are sure that everything fits it will give you the correct backspace reading for the wheel that you need. I have attached some pics of my car to give you a better idea.

64/5 Chevelle rear fenderwell is quite a bit smaller than the 66/7's. I have a 3" minitub and 17X11's which have about 5/8" clearance inside and outside, with rolled inner fenderwells. There is no way a 10" wheel will clear on the earlier cars without a minitub.
