Th2004R swap

[Steve66]

I'm starting to get things lined out to swap out my powerglide for a TH2004R in my '66 C10 and have a few questions. I'm under the impression that the driveline should work fine and that I'll have to move my rear tranny mount back a little and add the TV cable and some wiring for the locking torque converter. But what about the shifter? will the stock linkage work or is there something else I will have to use? Do the backup lights still plug into the new tranny? Are there issues with the cooling lines? I'd like to get a plan to sort out any issues before I start this and would appreciate any advice from someone who had been down this road before. FWIW this will go behind a freshly rebuilt 283 with a 3.73 rear end.
