Sub-frame connectors... Please build them correctly!

My opinion?? The OP is stating the obvious, anytime you can add structural rigidity, it will significantly reduce flex! These cars were traditionally "thrown" together, and can all stand to be completely gone through and stiffened through welding, even most of the already welded components! Is a spot weld every 4" better than one continuous seam weld? Of course not! Why did they take a little extra time welding the 340 K frames? How bout the torque boxes on Hemi, 6pak and convertible cars? Because just a flat floorpan with some stamped rigid gusseting is obviously "just enough"!!

I agree, weld the heck out of everything, and add the top flange to 2x3 tubing like the factory frame rails too while you're at it!! Good info included in this thread! Geof
