Also started another important part of the swap. A different transfercase. The Borg Warner transfercase is garbage. This is the second one it's had. The viscous coupler is seized up and makes turning in a full time four wheel truck really bad.
So I bought a parts Disco with a good LT230 transfercase that has a center locking diff for off road. And an open diff for on road. It works in high or low range. The LT230 has lower gearing I high range and low range.
The easy part is done. Now I need to remove a cross member, unbolt the transmission from the engine, unbolt driveshafts, drain fluids and lower it all out from below.
