Mr Paschetto, that Speedway stud is it exactly. I see the price has doubled since I added them 10 yrs ago. To level the steering rods for bump-steer adjustment, once you have the studs, one only needs spacer-washers and a carpenters level.
Yes- the heims are female thread and screw on by hand, with a jam nut. They retain stock toe-in adjustment capability. I add heim-joint seals for some weather protection. They're pairs of conical neoprene washers that cover the ball on both sides. Not as elaborate as the full rubber jackets like on Mangusta suspension, but adequate. I think I got mine from Pegasus Auto Racing in Wisconsin. They specialize in formula car parts.
Thanks but not so much wise as poor and trained as an engineer. My whole reason for all the suspension mods was to make the car safer for my wife to drive anywhere, any time.
