Bumper guard removal on a 73 Scamp?

Thanks Bad Sport.

Any recommendation on what type of grinder to purchase? I have a Harbor Freight right down the road from me, so I can pick one up pretty cheap. I'm guessing bumper removal is the only way, because there is just no room to work when they are on.

I definitely need to step up on acquiring some new tools. It looks like next weekends project is all lined up.
