Hello all,I need a little help,I'm looking for description,pics or anything really of the Union between a T 18 4 speed and a Dana 20 transfer,I'm trying to figure out a divorced 20 transfer set up to mate to a ZF S 5 42...I think divorcing it is my only option,I have a D 20 (courtesy of IrishCJ6)which had been divorced (badly by previous/previous owner) for playing with but I thing the input shaft is too short to work..im my head I need 2 bearings in the input but does the mated D20 input/coupler sit into /held by the D20 rear output shaft some way?the input shaft on the box I have is a 10 spline (slightly larger OD than output 10 splines)with a nut holding the gear on,I presume it was cut from its original mate to make divorce input,I currently have a T18/D20 combo in the truck but the 4 speed is a good upgrade for IrishCJ so I don't want to hack the Gbox output.any help appreciated thanks
