Any suggestions?

I just got my grandfather's old El Camino that is mechanically fine but got T-boned a few years ago. I am planning on getting a patch panel and just replacing the quarter panel. I have never done anything like this before and was wondering if there's a better (hopefully less expensive) method. Here is a picture. Any help is appreciated. Thanks!
(Ignore the missing wheel, I'm putting in new shoes.)

Mike, just any FYI for future posts, you cannot image link an entire album. You either need to post just the album link (like how I have edited your post to do so) or image link each individual picture.

okay, thanks. I thought links were against the rules.

Well you're linking a photo gallery so it is not a big deal. You could always just image link each individual photo if you wish.

This is going to look awesome. Post some pictures once it's done.
