do you have any now in hand to work with or sample from?
I made mine. I used the cardboard stock ones as templates. i made them out of like 1/8" or 1/4" plastic sheet then foam pad then vinyl. its posted in this forum somewhere.
The curve thing at the top is actually a piece of steel. it would be best if you had that part at least.
let me know what pieces you have and what measurements you seek - when you say front and back you mean both panels the doors and the rear quarters?
