Failing that it's just a bolt. Go to your local nut and bolt shop with the id for the anti roll bar eye end. They should supply you with a bolt, nut and washer(s). You'll need a large dia washer for the drop link side.
I think they are 7/16 unf.
Be sure and get grade 5 (3 dashes on the head) or 8 (6 dashes on the head).
If you have any real traumas PM me - I have to go get the hardwear to attach mine so I can get two lots and send you one. We have a great shop here in Weston, they do any bolt you can imagine!
