I'll take some pics and post later, I used an art carr winters shifter for a torqueflight 727 and made my own bracket instead of using their linkage. Shifter is great, shifts very crisp and never slips into the wrong gear. Its easy to feel the shifts even in the dark when driving at night. Swap nickle and dimed me half to death but wasnt too hard..off the top of my head here is the basics:
Had to swap flywheel for flex plate
added trans cooler from an 07 ford 6.0L diesel (it was big and cheap)
had to weld a bracket and gussets on the front of crossmember because it was too far back for the auto trans on my formerly manual truck
swapped transfer case input shaft and extended transfer case shift linkage
resized driveshafts (front got longer, rear got shorter)
...I'm sure I'm forgetting some stuff along the way, but those were the main points.
New trans is great, triple disc converter, all billet shafts and upgraded parts, fully manual valvebody and I can even manually adjust the line pressure/shift firmness. Overdrive is the switch on the gauge cluster and the button on my shifter locks the TC.
