Hi all, where's the best place to buy some of those diamond plate quarter panels. I've got a rusty tub that needs cover. It's only cosmetic cover (for a 72) as far as I'm concerned, so aluminum is fine. I plan to paint them black anyway. I'd ideally like the full panel that goes all the way to the door opening, but open to just the corners. I'm not seeing any used ones readily available. Also, how do they apply? Just start drilling holes and riveting??? located in SoCal. Thanks for your replies.
