i just kept the nuts and bolts with what ever parts came off, put the bolts in the holes to keep em safe and in place for your memory.

loose bolts got grouped together on the windshield cowl, what GM made that shelf for. wire plugs only go one place, when you lay the harness back over the engine the plugs tend to lay right where they came from, i even had a injector plug land dead on the injector, all i had to do was push it on. aka putting all the plugs back on is mindless really.
