MaTTi ... Call up rick at BTB and ask him, he sourced them direct from Fox and Im not sure of the numbers
4" lift springs also from BTB as well ... I have sets for both the 4" lift and the 2.5" lift for the next build
Letterman, anything you want to know about the engine bay and the complete setup let me know, I have over 1000 pictures
Cheers
Steve
Thanks Steve. I’m in the middle of a 5.7 swap and your build has me dreaming.
