Hyundai Transmission Removal (repeat)

I have a 1996 Hyundai Elantra wagon with 103000 miles on the odometer. It has a 1.8 liter engine and a manual transmission. The clutch is slipping and needs to be replaced. I elected to try the job myself. All went as well as could be expected up to the point where I had completely unfastened the transmission from the engine and the half axles. At this point, I couldn't seperate the units. They will pull apart an inch or two, then they insist on snapping back togather. I assume the driveshaft is stuck in the clutchplate, and that if I could get the parts aligned perfectly, they would seperate easily. I am supporting the transmission on a platform bolted to a floor jack. I would appreciate any ideas on how to get the units aligned. I am running out of things to try.

Please help ! !

Thanks

P.S. I donated before I lost my first letter.
