67 dart GT drivers seat base

Looking for a drivers seat bottom frame for a 67 Dart GT with bucket seats. I have the new seat bun and seat cover but the springs are broken and bent. I think this is a common part from 67 - 69 but if not someone can straighten me out. I know this is going to be expensive to ship so I would like to get the best one possible no rusty busted down elephant *** squised junk I allready have one of those. If you can help me out reply and I'll get back to you.
