Arde,
a while back, i was looking at the suspension techniques catalog ... and for some reason, i have an ebay auction tagged for a set of bars for a 79 to 81 528i (e12) that also fits a 77 to 82 630csi / 633csi (e24). the set product number is 52015. seems like i remember reading that these bars fit our cars - but i can't lay my hands on whatever i read that said this ... so please don't take my word for it. interesting enough, i just looked on carl nelson's site, and i didn't see the swaybars listed.
i bought a used ST front bar from Mario at VSR a while back, but it doesn't have any of the mounting hardware.
so question to anybody reading this thread - has anybody corresponded with ST to find out if anything they make still fits our cars? i will try to reach out to them this week and ask the question. if the answer is that they don't make anything - i will ask how many units they would need in a group order to revive the product, and then we can see if we have enough interest to do it. i have sent an email to ST - will update the group on what i find out
