I have an F150 trans in mine, and I have kept the torque tube set-up, but it's as much work either way. I cut the mounting plate off the rear snout, and made a duplicate from 5/16" steel plate. the steel plate mounts the torque tube, and is bolted on with the F150 (or T5) mounting plate. Be aware that a T5 will need to have an S10 housing to get the shifter forward. The long tailshaft of the F150 (T5) I cut and splined to take the early universal joint.
This is a very laborious job, and expensive, and in retrospect I would have left the long tailshaft and opted for an open drive banjo from a pickup. There's a company called Hot Rod Works, and another called Chassis Engineering who I believe both make bolt-on crossmembers for locating wishbones. The only wishbones that are really strong enough are the 35-36 ones. There is plenty of info on the HAMB for doing this.
This is my conversion, I chose the F150 trans because the shifter is in the perfect spot for me.
