Anyone using an Addco Rear Sway bar?

I've got a brand new ADDCO rear anti-sway bar kit in my shop that I bought for my A body. It was listed to fit both A & B bodies. The link bolts are 7" long, grade 8. They have a 1" threaded section. The spacer for each link is 1" long. The rest of the bolt length is taken up by the bushings.

Thanks for the measurements. The links that Addco sent me were 5" long so I knew they were way too short. I understand that I will need to adjust them but I can't make them longer. I am going to mock everything up & track down some grade 8 bolts. I am going to lower the rear first & weld permanent mounts to the frame. I have learned quite a bit doing all of this research but it will all pay off in the end.
