I had these in my garage from OPG - they sell on their website on sale for $37.95 plus shipping. I will sell my set for $30 which includes shipping in the U.S. My set is still in the bag never opened - pic included.
The set is now sold pending payment by Walt. Doug, I'll put you next in line is the deal does not go through.
BuickOne never got back to me and since it has been a month I am listing this part for sale again - DugsSin is next in line, if anyone else is interested please let me know.
Glad they arrived safely - good luck with your control arm conversion! P.S., if you don't already have a rear sway bar, OPG has a one inch rear sway bar that is a little cheaper than the stock size - I bought one for my own Buick which will be a summer project.
