I would be careful about that he will package it up at materials cost if you arrange shipping comment. You may end up paying for a couple hundred. Dollar crate job.
Been down that road years ago with a set of bucket seats I bought. They were basically just frames. He said they would go UPS. So I told him just fold them duct tape them and put a label on them. No he takes them and builds a crate to ship them in. I guess he still has them.
