1: you want to use the first TRF dampers on your list.

2: no, springs can only be used by bore size. The older design springs (small original bore) long or short can work. None of the big bore springs will work on small bore dampers.

There are option parts you can buy to change the upper shock mount to use the big bore lowers them) but really the original TRF dampers are the ones this chassis was designed for.
