I was thinking of using a 200 4R, but after reading this thread, a 42RH seems like a better idea. While it appears that the A500/42RH was used beginning in 1988, what are the best years and applications to get cores?
Later models have the stronger torque converter hub. I believe from 92' on, I could be wrong though. I went with a '95, I haven't carved into mine yet, but I'm willing to bet it has other goodies that will be helpful.
