Fook!, I'll be happy when I can get to that point. I've finally managed to get the front u-joint spline to move back about an 1/8", but it's not staying there. Like it's spring-loaded or something. Not so sure there may be something amuck on the butt-end of the drive shaft where the splines engage the final drive. I'm going to continue to slowly pull the rear frame section back and see what the front splined joint does. If it looks like it will continue to slide back and off, we may be okay. I can deal with the final drive splines later. .
