just thought I should make a correction. On the second drawing you see the angle iron piece, in the picture of that part the angle is turned 180 deg. I like it like the picture. It will work either way but I did screw up and draw it turned around.
I also wanted to say if you split a piece of vac. tube and put it on theedges that touch the paint you will get no paint damage.
I hope someone gets use out of this ,they are very ridged clamps and hold very tight.
