I'm trying to use a modern TLR 22 slipper setup, but I'm having a hard time getting everything to work properly. I think I may need to find a longer slipper spring.
B4 slipper plates work well and space out with the standard large diameter springs

Charlie - Good recommendation. I also like the idea of using a 4/40 screw straight into the threads of the top shaft.

I got some work done. Arms and towers mounted. Factory Works supplied the towers as well as the front carbon brace for the hinge pins. I had wanted to use an RPM front bulkhead for the added strength, but I don't have any of the correct versions left - the ones with the top threads for the top plate. I hope the fact this bulkhead is brand new means it's less likely to crack.

Titanium hardware is being used throughout. I am using the LXT spindles and carriers for the added adjustments. However I think I will swap out the long armed spindles for the standard ones. Does anyone have any input on this?

Looking great! LXT carriers/uprights with Jrx2 spindles is half of the Jammin Steering enhancement kit. Here’s my break down of the kit..

Getting closer now. Got the spindles changed to buggy length. Also swapped the steering ballstud to the underside of the carbon steering rack.

All black titanium turnbuckles with RPM ends. Very thankful for JC Racing. They have made it so running and racing these vintage cars is so much easier.
