Anyone use OC Auto Carpets? (Auto Custom Carpets)

[LS short box]

I've used ACC on a number of projects with good results with the exception of my current 80 Camaro project. Many creases that I thought would come out over time but no luck.
Pic of the insulation I added to my 68.
I only used the ACC floor carpet on my 68. I used what's called trunk liner on the back wall of the cab. Got it at a local fabric shop for about $20.
