Wire harness chassis clips

Hey Guys. I have a huge truck project going on right now. I have removed a ton of the wire harness clips that attach the harness to the frame. As well as all of the push clips on almost every plastic accessory on the truck. I need to buy all new stuff and the Amazon crap has never worked well for me. Is there anywhere to buy a full assortment pack of GM specific clips, and push tabs? Or any aftermarket stuff that actually works well. Thanks for the input.
