Well, after posting this awhile back, both here and several other classic mustang enthusiast forums, I've tallied up the various places people suggested, then went to these various places (websites and catalogs) and found that only one place beat all of the others for pricing, and in my estimation, knowledge about classic Mustangs specifically. The place is called Harris Mustang Supply. They don't have a website, but they do have a catalog. You can call in your order and they'll ship it right out. Generally, if you call there, they already know what you need when you tell them what part of the car your working on or restoring. It's almost weird, uncanny how they seem to just know, lol!
