Ok so I see alot threads about alot of people on here that are supposed to be helpful!!!
So where the hell are you????

I posted a thread awhile ago and still havent had any luck with my driveshaft,

at the beginning of the year I had my th350 rebuilt, had no problems getting it in the car,
Now I go and replace my flexplate, When I took the driveshaft out, I had to pry it out with a big screwdriver wasn't too happy about that.

Now when I try to put it in,after I changed the flexplate, it does not set all the way into the trans so I can get the U-joints in the yoke of the diff., I have asked a few people and they said check the yoke and make sure there is nothing blocking it, OK done nothing there, I also took off the tailshaft cover, and cleaned the splines, still wont go in far enough, to get the driveshaft in.

any ideas about what I can do, or what might be the problem?????
thanks for your help guys!!!!!

Sounds like the shaft was too long, and it may have a gauled the spline. Take a sharp pick and see if it hangs up on the splines on the drive shaft.

It also make a difference if the rear is hanging when you jack it up. If you suport the frame and let the rear end droop it will be harder to remoce the shaft.

well, I tried that already, the rear was up on jack stands when I have done all the work..

I still dont know and its starting to **** me off cause I havent driven it for about 2-3 months!!!!!!!!
