Early Dart stone shields

I e-mailed the seller for the length of the ones he has for sale and here is his reply
.
Stone guard dimensions: 2" wide, 8" long, and folded over wheel well flange is 7" long. Hope this helps !
.
And mine on my 64 Dart GT is a little over 12 inches long so I guess they are differant also the ones on mine are held on with a body clip on the backside with a stud that gos in a hole in the quarter close to the wheel well.
