You mentioned the truck coming with bins full of new parts , When i start stripping a truck to rebuild as the bad or parts that need to be replaced I start a list and start shopping for all these needed parts on ebay and anywhere else I can find the replacements on a deal rather than opening a catalog when the truck is painted and having to start paying retail for parts that could have been bought at a discount over the course of the build ,Also they are already sitting in my bins waiting to be installed ,Not hunting for parts on assembly saves time and a ton of cash along the way . Also all the parts that can be saved are media blasted primed and painted then wrapped and stored away until reassembly time comes , it really saves time and $
