It never fails. You're in the shop and putting a Duramax back together. That bolt you need to finish off the front cover has gone to the same place that all of your 10mm sockets have gone. You put in a brand new, zinc-coated one and the rest just don't look as good. Or maybe you're missing more than one. Get the whole set and be ready to go with the DHD Front Cover Bolt kit.
