I sincerely appreciate everyone’s contribution and advice on this thread. This is my first go-round trying to build a car and there are some aspects I’m good at but the mechical/fabrication part is NOT one of them. Sorry if some of these questions seem a little elementary.

I realize it can be lowered but can I lower it and leave the trans/torque tube stock? I’ve heard that if you lower it, the trans and torque tube no longer seal.

Assuming I stay stock, is there a way to put lowering springs in and still go with the Dynaflow/torque tube set up? I’ve been told there isn’t. I don’t need it on the ground but I’d like to drop it 3” or so.

Can anyone tell me if this Jag set up would work on a 55 as well as a 56 Special/Century? I have a 55 and am trying to decide whether to rebuild the Dynaflow or mate to a 700r4 via adapter and swap out rear end with something like this. My factory 322 is rebuilt.
