Uh oh. Seems I'm too late for the party. I think you're going to be VERY disappointed with the fit of the mustang skin. I went through a couple of them before I said screw it and found a used quarter.
Since you said waiting for a sale, I assume you bought it at CJ's or something?
Every skin I had was either too long overall, or too short at the front bottom. And you can cut and splice and butt weld it to the correct shape, but in the end, I found used better...
