I just completed the install today using this part: 5GM-863-007-CA9. I got it used from AH Parts near Sacramento, CA and had it shipped to me in FL. The liner fit perfectly over the pads, not a single bulge or wrinkle. The spare tire and roadside tire change kit also fit nicely in the carpeted well. It looks fantastic.
Whoa, that looks fantastic Jgilber0. Thanks for confirming the P/N and providing the excellent pictures. This is now a definite adder on my list of improvements.
