If your 3600 is like mine, the front is closed-drive-line. To go to a single piece you need to open the forward drive-line with a new tranny. The T-5 swap would be a good time to go that way. The combo drive-line has a seal just forward of the mid-bearing, where the open part starts. This seals the rear of the stock tranny as well, so at least the output end of the tranny needs changing to get rid of the torque tube.
Current fleet (subject to change w/o notice) \'49 GMC 3/4-Ton , 60 Austin Healey Frog-eye Sprite (some assembly required), 2011 Dodge Avenger, 2015 Jeep Cherokee. No, they don't all run. My other ride is a (B737)no, (B767)no, A320.... Update... was Embraer E190, now Boeing B787. Knowledge is a wonderful thing, but ignorance means you don't know you can't do something.
