Thanks for the information, but I can't seem to visualize How this will work. The rearend has a fixed pinion yoke and the rear of the transmission has a fixed yoke, so "where is the slip yoke"?
That's the parts you have today. Mine has the slip yoke on the transmission. Mine is a '55 1st that started with an open drive line but the parts are not hard to swap if you can find them.
