Weight comparison between a Hemi Dart and a Hemi Barracuda.

Well let us narrow this down even more to the rear torque box only, that you found on the Formula S BB 4-speed cars, and most, if not all of the SB manual trans cars.
Have yet not seen any picture of any of the SS hemi´s having the front reinforcement box, that the convertibles had.

That is correct…we’re not 100% sure if they got the front boxes or the leaf spring support. In the notes I got from Bob Tarozzi he has all the specs for those reinforcement but nowhere does it say they were added. However I believe the answer lies in what was on the factory 383 cars. These BOs and LOs started life as 383 cars so if 383 cars got them then the Hemi cars got them. Last sentence. 0A506154-5E10-4F67-B110-5CE6B9C9C89B.jpeg
