not knocking Corbin but i just had a custom seat done by Danny Grey. They were absolute awesome to deal with. what ever your doing they can help you out.
If you just want to recover what you got, send them the pan. if you have to make your own pan there is plenty of info out there. I did a fiberglass pan and it came out flawless.

I can honestly say that it was a pleasure dealing with them and i had a full custom seat from Glass to Ass in less than 5 weeks . 2 of those weeks was to get the design right and 1 more week to get the stingray hide.
you cant beat that....
