Motorhome 727 trans in an A-body?

I haven't gotten any pics of the trans but the guy who has it said the driveshaft bolts to the back of the trans. That doesn't bode well for me.
If it bolts to the tranny it sounds like it has the park brake drum on it. I have the long style tailpiece for a 727 that I don't need. PM me if interested and I'll go find it and take some pictures....
