Well, need to look on that trans to see if you have a seal in it, and where its located in relation to your output shaft. Chances are you'll have to have some machining done. You can do it though....just have to run a flange off the rear of your trans output shaft, etc...
To have a slipyoke type of setup, some extra machining will be necessary....a good, well equipped machine shop with spline cutting capabilities and heat-treat equipment can do the job.
Do a search, theres places out there that do this....
