I just finished seam welding the entire chassis for my 71 chevelle. I've heard that i should weld gussets on the mounting brackets of the front lower control arms. Also on the rear end where the upper arms attach to the chassis. Also to weld closed the holes in the frame that are close to the front lower control arms, i've heard they are prone to cracking there.

Does anyone have any pictures or links to pictures that show any of this. I'd like to see exactly where to brace and which hole to fill while i'm this far into it.

Thanks a bunch,
Kyle
