I bought a replacement shaft for a 90's dodge truck for my b body. Comes with a u joint, a slide shaft, its like the ultimate $40 conversion shaft grab bag of pieces parts that other "steering component" companies charge $300 for. Let me see if I can find it...

EDIT
HERE IT IS. this slid right on my mopar manual steering box splines in the b body. Same manual box I have had in a few cars. Went right on.
