I was wondering what the best way to cross brace a frame is. I've got an 81 k10 sub. The frame is solid but I would like to add some cross bracing. I don't want to box the frame, I would just like to add some strength to it. So I was wondering which would be better, either use some sort of angle iron and weld it on either end to the frame rail or use some tubing and weld it up. I don't want to box it because I would like to keep some of its flexability. Any suggestions would be great. And thanks ( to who every did it ) for this great website, it has been a great help and it is super cool that the basic membership is free, because I'm poor and can't stop spending money on my truck!!!
