Gear Vendors in 69 Dart

I installed a GV in my 71 Scamp and my combo is 440/727/8-3/4 3.23 gears and over all is was not too bad of an install. For my install I did the clearance the tunnel and it worked out but in hindsight I would like to clearance the tunnel a bit more. The areas that had to be clearance is around the transmission to GV mounting flange and two areas around the top of the GV case where the two sections of the GV bolt together. I spent extra time on the driveshaft and pinon/GV angles to ensure no shaft vibration. My 440 is making 530 ft lbs. of torque so for me the 3.23 gears are a good compromise between fun burnouts and highway cruising/MPG. The only ting I did not like about the install was that GV uses a headlight dimmer switch on the floor for gear the splitting and I did not want to mount a second switch and get confused on what switch to use so I mounted a momentary switch to my floor shift lever so now I use my thumb instead of my foot and it works fine for me. I would also recommend taking time when doing the wiring install not that the GV wiring is complicated its just from my research most problems are from people rushing/halfassing the install and having resulting problems from said rushed install. Would I do it again yes, GV has great overall customer support an the highway cruising alone make it worth the time, money, effort.
