Modified Spring Plates For Easy T-Bar Replacement?
 

Would there be any advantage to being able to replace or re-index the rear torsion bars without removing the spring plates and messing up alignment settings?

I was thinking the torsion bar tube on the existing spring plate could be modified as follows:
- cut off the end of the tube, that has the splines that mate with the splines on the torsion bar.
- weld collars around both cut ends of the tube.
- replace the tube end by bolting the collars together.
- now you can replace or re-index the rear t-bars by disconnecting the rear shock, letting the rear suspension droop, removing the tube end, and pulling out the t-bar.

What do people think? Would this be a worthwhile aftermarket product?

Interesting idea. One problem is that when you change ride height the Alignment changes so it has to be reset any way. You would be alot closer though by not having to take it all apart.

Sway-a-way spring plates have this capability. Different implementation though.
