The 261 was installed w/o transmission. Piece of cake. The transmission jack I borrowed with pitch/yaw/roll (?) was a dream come true. Perfect alignment was easily made.
I have bench pressed a tranny in place on a '54 Chevy Station wagon back when I was more capable. I have a friend with a tranny jack like that and it makes replacing the tranny in my F250 do-able. It weighs in at a bit over 200 lb. I could probably still bench press install the 3-speed in my '51, but don't plan on trying it.
