They look to be 3/16" thick or so... The brackets I planned on using are 1/8" thick, but as I see most of you use at least 3/16 or 1/4" angle iron, which is probably what I'll end up using. Thanks for all the help fella's!
I have a single tab welded to the chassis on each side of the car.... .100 thickness, 2 bolts per side
