Hey Topcat, as already mentioned that's a good idea for any high performance e-body. The true hemi cars were actually built on convertible bodies with a hardtop added. The torque boxes were already on the convertibles due to the lack of strength in the body since there wasn't a roof. So if you see someone claiming they have an original hemi cuda and you want to check it out, look for the torque boxes, they would all have them. Just some interesting information where the engineers came up with the stiffer body for this torque monster! Weld in frame rails and torque boxes are great body stiffeners, the HEMI is a great body stiffener all by itself but in another area of the body that we shouldn't mention!! LOL
