Kroil, it's a miracle! As the first big step to getting this rust pile up and running again, I've been trying to get the transmission shift tower off. Slowly wedging in putty knives, soaking with PB Blaster, then gradually driving in thicker implements until I could spray penetrant directly onto the shift forks and gears, but not any major progress until switching to Kroil.

After about a week of squirting Kroil into the transmission, I finally felt the tower start to move.

Anyway, pretty happy to make a little progress.
PS, can anyone tell me how to properly post pictures here?
