62cutlassconvert, yes that is true with one piece drive line configuration, but a CV joint and center carrier bearing setup, things are set up differently. The first time I have any problems with my current set up, I will go to a one piece driveline. I have modified my upper control arms already, so the pinion angle can be easily changed as needed to get the driveline angles parallel. Having installed different rear springs (stiffer) and having the ride height one inch taller, the problem of the driveline hitting the body tunnel will not be a problem. That’s why the factory used the carrier bearing design in the first place, clearance issues.
BTW the machine shop is happy with the flexplate and thinks this is the way to go. If they would just finish the eng now!
We are doing 2 cars with this conversion and had planned to shorten the front shaft. But sounds like you have some practical experience here that we can learn from.
The TH200 does appear to be significantly shorter than the T5.
So I guess you moved the center carrier support crossmember back on the frame and then shortened the 2nd shaft?
Regarding a single shaft, we have discussed that too but thought we would try the shortening of the 2 pc shaft to see if it worked. One car is running 1″ shorter/stiffer Eaton Detroit springs-think there’s enough clearance for a 1pc shaft?
