I like that idea! lol

I just put a little bead on the flange so that way I can just take a grinder to it real quik if I ever wanted to take mine off.

That's just the thing - These guys aren't even worried about flanges, they  just crawl under your truck with a sawzall and chop it off.  Then they don't have to worry about rusted bolts or anything sticking or stripping.  They definately have some huevos making all that noise and not getting caught.  I mean, I could see maybe a pipe cutter, but they are definately using sawzalls.
