ratterman, I saw over on the HAMB that a guy just had one of those spring pivots break. I have that style on 2 cars. Speedway used to make their pivots a different and better way. I intend to replace mine with some from MAS. They don't cost much so you could build with the Speedway units. But I'd consider getting welded pivots eventually. I brought a pivot to my Wed. old boys lunch which consists of 2 machinists, one restorer, one rod fabricator and me. We all agreed that the Speedway pivots are sketchy. Everything else that I've bought from Speedway is good, and I use lots of their suspension stuff. A longer spring will provide a better ride. As long as you have room for it. Do you have a reason for using Left Hand Thread tie rod ends and bungs? Right hand is by far more common. Good luck with the project.
