I got a set of these from pat he said they wore off his sled.
They had a lot of cracks in them he said weld them up and go race.
He said he would trust them, I wouldn't so they're hanging on my wall, if you're interested in buying them from Pat ask questions on what kind of shape they're in and make your own decision.
Hope this helps. Pat was completely honest with me when I bought these, the cracks weren't a surprise.
