any kit still has to B adapted (to their way of engineering) and is expensive. I have so many comments on this install I cant concieve how to enter them (several pages w/my kybd skills, hand arthritis, learning disabilities, etc) so will send U something of a "hi points".
A different transmish is suggested (NV3550), I no "Too late" extensive research all ways indicated in pre-project mods;
A 'typical bronk vendor' bell housing 'hang off bolt' was used at this member;s shop (C sig below);
A Ranger hyd clutch ***** will fit in the fsb bell;
A 4500 is used for very heavy (diesel) apps, needs DS changes and is often chosen (my consideration) for the 2 PTOs & possibility (also e-brake) or is that the ZF? another operated on hydro clutch (yeah, think so, sorry).
Last. many have done this mod on CB. There is a prts list and tech write up over there formed as a 'sticky'~
