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

A-body Joe: Yours has a factor that helps considerably that has not been discussed. How much of the floating connecter attaches to the sub frame section. You have a considerable amount of material that make the side wall of the tube transfer the stress well.

As for what I do... There wasnt really any reason for all that but no, I do not hold an engineering degree, but I design sheet metal structures on a daily basis. Machine equipment that we assess all of these same factors on and in the same manner.
