Get a piece of plywood for underneath the truck (Or at least a tarp) when you work on it, because you'll never find nuts n bolts in the gravel, until you've given up and replaced it. Also always get about a 1.5ft square piece of thick plywood when you use jacks or jackstands, etc. Cinder blocks can break. Mainly just keep it as clean as possible. Don't do inner engine work on windy days. Then Have fun with your new project.
