When I use this decoder https://www.jeepz.com/forum/vin.php and substitute a J for the 6 (6T=>JT) it gives me this which is consistent with the description.
Can someone try re running the build sheet with 1JTHW6612JT181355? Thanks.
I have the JCR ones and had to shim the rear about 3/4" to make them even. Also their pinch seam strap extends the whole distance but the pinch seam on the truck steps out about 1 1/2 inches at the rear and has corrugations so it does not sit flat.
