727 Tailshaft removal ?

Kent mosby said
I am prepping to install the gearvendor OD. Driveshaft is out and exhaust is out. I was looking at the access plate for the tailshaft clip and saw that it is not very accessible. I know that I will have to drop the transmission a bit. Car is on a 4 post lift so access is easy. How far can you drop the rear of the transmission without damaging things like the front mounts, transmission cooler lines or anything else? Can I support it on the transmission pan while installing the adapter? Any tips to make this easier would be appreciated. I will go look at the FSM right now.

I had to do this very procedure on a new TCI BB 727 because they did not change the tail shaft bushing and I can tell you that I could not get the tail shaft housing out without putting a pry bar on top of trans in the ledge over the bottom pan and leveraging the bar against the frame rail by using a floor jack. Yes the exhaust, drive shaft and cross member all had to come out. PAIN IN THE ***!!!!!
