wheel clamp for alignment

I found the Hunter clamps used and bought them on a "make offer". They are in great shape, very affordable. My Hunter turn tables are not shown but got these a bit back. Advertised a wanted ad locally and after about a year, I got a call from a local who said 100.00 bucks and they yours...how do you pass this up? Been slowly putting my stuff together. My son bought me a nice caster/camber gauge for my birthday, same model they used at the shop where he was working at the time. Slowly getting set up.....
