I enjoy talking with other that have a engineering background and thank you for the explanation of the "I" beam because that is in fact the exact scenario I am duplicating. The 2x4 rails being the top and bottom of the "I" and the center bracing of the chassis which is also connected to the steel interior via 1/2 bolt. The fiberglass floor board is sandwiched between the 2 pieces of steel. The steel cage that we have built and put into place also is welded to the steel thus creating a close resemblance to a Unibody.

Some mopar fans compare everything to the 60-70 steel cars and I will never argue that my car is as safe or even close! I will say that custom33 has more support and reinforcement then the majority of street rod companies.
