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.
