After cutting 2" off the back and tapering it to the front, This is where the difference shows up! (The piece that's too tall with a pencil line) Little worried about a drip edge. Sides will be the same angle in, as the top that's marked comes down.
Spent two days cutting, tweeking 1 tube a little bit in two directions, because eyeballed wasn't close enough! And it's for Alignment. Second picture shows the rear bumper tacked on.
