@DannyP posted:Well, being as I have a Vintage Spyder, I already have coilovers in back, but it is still a swing axle. They are QA1 Proma-Star,10-14", 275 lb./inch springs.
The Vintage uses a heim joint at the front, trailing arms are fabricated steel tube.
The best part is, no torsion tube to get in the way of my dry sump pump, and I can easily adjust the pre-load on scales.
I found this online. Looks pretty simple. So simple, in fact, that I'm going to buy the spring plate caps to heim joint bits and some cro-moly tubing and take them to a pro welder I know and see what we can come up with.
Thanks for posting your shock info, I was going to pm you for it. Next time you have your clamshell up, can you take a few pictures for me?
