Water and rust, hmmm, hadn't thought about that. The hole/threader tool looked cool but I didn't see them using it on a hand drill. Not sure a hand drill is the best way to go, not very precise. Some of the pieces that have holes are already integrel to the frame. I like the tabs idea, seems easy enough and a lot more solid than my cheesey tapped holes. Tabs it is. Thanks guys! Carl, my dear sweet wife will get the first ride in my buggy. You can have the 2nd ride if you promise not to tell her how much I have in that money pit!
