I posted an awful lot on fitting this trans with a stock auto on the floor linkage, trans lines, trans cooler, cooler thermostat, kickdown linkage etc. I included what parts I used off junkyard donors, and decent pictures to follow when doing this swap. See my build thread "67/68/69 cuda dilemma" for all that information when installing a 42RH or 46RH. I chose a 42RH. The wiring and solenoid kit is available from PATC for the 46RH. They do not make one for a 42RH. I fabricated my own 1 off crossmember that's similar in design to the UScartool one.
