hello all, I am currently about to start boxing the frame rails on my 35 ford chassis, I've removed the X brace and cut the boxing plates (11 gauge)to tuck neatly inside the factory C channel frame. question is,.. if you mig weld the plates in, and then grind them for a "smooth" look, doesnt that extremely weaken the joint? I'd much rather have a weld bead on my joint than have cracks when the car hits pot holes etc. driving down the road. any of you experienced hot rodders have good advice for me? thank you in advance.
