Well, just to say I haven't abandoned this project, the t4 is now resting with all my other old jeep drivetrain parts. Its being replaced with a np435. And while everything is out I'm putting 2 stics and the 300 is clocked 1" higher than the 435 bottom. And I'm to build a new bad dood skid plate. I'm taking the no aftermarket adapters approach. Only high precision tools used so far are a drill press, high powered dremel, and a plasma. The 300 to 435 adapting part is done, and I just got the bellhousing bolted onto the 435. Its gonna be 2" longer so I'll have to call up high angle and order new driveshafts.
