The defects are in the lat pull-down attachment and the bench when it is in a slanted position. I would call the company before assembling to make sure you don't have to do it twice. I'm not familiar with the model you bought, but it doesn't sound anything like mine. I was contacted by mail, and then had to call to get delivery of the upgrade parts. You're not kidding about primal scream! I'll have to make sure there are no neighbors around when my new parts come.
