I came across these traction bars that I have no use for, made by Chassis engineering. Should fit 64-72 Skylark/GS cars according to the manual. What you see in the pictures is what you get, I've been trying to figure out if it's all there, but there's only one of the small sleeves (see pic), and I can't figure out the "delrin bushings" which should be there according to the manual. These bars and hardware feel like nice pieces, quality stuff, but I have no use for them, and the set might have to be completed with some bushing/sleeve? If you know this kind kind of stuff you can probably tell (chime in on) what we have here. I don't know anything about how these work technically, or mounting them etc. $40 + $20 to ship to the lower 48 Hopefully someone can put these to use!
