Im happy enough with the product but no template is very annoying. I can't find anything to download either. Is there somebody out there that would be willing to scan and send me their template?
Basicly what I did was measure how much of a margin you have on all four sides where it scoops in and mark it out on the front bumper, try and go conservative at first and test fit it. It probably took me a couple hours to put mine in because I prefer to start small and then trim it with a knife.
But yeah your right a template would take the guess work out of it. But its good to know you would have to cut a crap ton out to cut too much. So just take your time!
Lost the template in the 3 or so years from when i got it and put it in. Grease pencil on the back (lipstick works too) of the insert and use that to mark your cut line. cut on the inside of the line, better to take off too little than too much. take your time.
