Going to coilovers involves a torsion bar delete, and the shock towers were not designed to carry the full rear weight of the chassis+engine+transaxle (like the torsion bars were via the spring plates).

Rear coilover choice is a personal preference based on your own due-diligence (research, purchase choice). You have a long wheelbase (LWB) car, and I believe as long as you order coilovers for an early LWB car, you should be good to go. I don't think aluminum vs steel ('69-71) LWB trailing arms matter, since the angle of the shock tower was likely not changed when going from steel LWB arms to aluminum.
Thanks!
I purchased the reinforcement kit from elephant racing that braces the shock tower as well as the area where the 935 spring plates mount. I am planning on doing these mods while the car is in body work. I also have to weld in the rear sway bar mounts to the chassis.
