SMA chrome Trailing arms

[8500lbs]

I just bought some SMA Chrome trailing arms, used for 200 bucks. I am not sure if I got a good price or not and was wondering what you guys thought?
They have been used and the polyurethane bushings have been replaced with rubber ones. They say the rubber is better but I dont know enought to say either way? They did Chip the chrome on them and I thought that if it looks to bad after getting them on i can just sand blast and powder coat them. Here are some pics.









Thanks for any advice and time.
