[Frank Miller]

I took an old driveshaft yoke and cut it off. Welded a plate on it to keep the oil from coming out of the back of the trans. You might be able to get away with an old yoke but this was my convertible with the X frame and there is no room with the overdrive. If you have a straight drop it should be fairly simple with a floor jack. Any other type of jack can be used to support the motor. Even the scissor jack out of your modern car with a block of wood my do it.
Not sure how good you are at fabrication but I made a jig that fit in my floor jack that I was able to bolt my overdrive to. Kept it from slipping off the jack and held it at the right angle.
Good luck.
