really, that's news to me. i'd love to see a picture of this. every roll bar, stabilizer bar, anti-roll bar, sway bar that i've ever installed had end links of some type or fashion. and i've installed a bunch on chevy's and fords.
As requested. ALL factory 67-72 GM A bodies, (Chevelle, etc), and maybe later attach the sway bar ends by BOLTING to the lower control arms with no end links. Thusly.
