I have a Fox Body Mustang Restoration book with the SA Design logo who makes a ton of these books over the years for Fox Mustangs, SN95s, New Edges, and etc. This is the latest edition made in 2019 stamped in the front page.

It has all color codes, door codes, lists of modern performance modifications. I paid $35 for it at Carlisle, looking to get $25 shipped for it.

I also have an older technical reference manual I can sell for $12 more. I took a quick picture, so it's a bit blurry.

I accept Apple Pay, Google Pay, Cash App, and Square.
