That seems to be why more and more folks are using parts from newer cars on their older muscle cars. cheap and easy to find! I haven't found squat worth using in a bone yard in a while, all that crap seems to get crusherized anymore.
I've had a lot of bad luck with reman units from time to time, I've gone thru four starters on my mild compression small block, alternators, and had to replace my master cylinder twice already. It's always possible.
