Re: Transmissions which one? 71 K10 standard to auto

It requires not only the 4x4 th350 but you’ll need the th350 to 205 adaptor, 27 spline shaft coupler, and to change the transfer case input shaft from the 10 spline coarse to the 27 spline fine, to do it right any way. There is a bit of a short cut to the different input shafts that isn’t as strong. Torque king and others sell a 10 spline to 27 spline conversion coupler. You can get the case adaptor from torque king, ORD and others as well. The transfer case mounts in the same place with either transmission so the driveshafts stay the same length in case you are wondering. Any 4x4 th350 should work as far as I am aware
