Thanks, good to know ahead of purchase. Original factory steel will last 50+ years, no reason steel replacements shouldn't last as long. Especially since the car spends most of it's time in the garage.
You put any spring wrap around them like the originals?
They come with the spring wrap already installed like originals.
Yep, 2 1/2 turns out, set with vacuum gauge, correct F4 bracket and the primary throttle shaft has newer bushings in it, no play. I am pretty confident its the throttle cable itself, I might have gotten a 2bbl cable when I replaced it 20 years ago.
