Looks good. Never too many Silverado builds if you drive a Silverado and your getting ready to start yours. Was the 1/4" ABS something you had laying around or are you using it somewhere else, like mounting amps or building amp racks with ? I'm getting soooo close to starting on my truck but I'm still undetermined on amp rack material. I'm doing the rear wall rack like Rick. I'm going to try to utilize every lat bit of space back there for it. HPDE is an hour and a half drive away and only in 4x8 sheets. ABS is close by and I can buy it in whatever dimensions I want but I don't know if it's going to work at 1/4" thick for a full size amp board. My LMI seat lift showed up today so I'm going to install it tomorrow and determine what I'm going to use for amp rack. Just curious if you were planning to use ABS ?
