If you look closely at most of these 1962 through 65 Mopars after adding a high horsepower engine, these vehicles develop body alignment issues with fit and finish. This is especially concerning when most inner fenders were cut out and clearance was given for an exhaust system in the 413 Max Wedge vehicles. The end result after these cars were basically ran wide open throttle and the engine wanting to torque hard on the driver side caused major structural issues to the frame behind the shock tower. The end result gave an unappealing at a glance, door jam to fender uneven gap. This also caused the doors not closing properly. Yes, I can agree that installing an additional point, firewall extending past the shock tower with the roll-cage will aid in the reduction of such issue. However, it is of our belief to structurally reworking the area of concern directly. We felt that this design would not only correct frame strength but also alleviate still the issue with frame twist. A roll cage ran through the firewall running vertically and turned down past the stock tower would still present an issue with twisting the frame under a wide open throttle condition unless you add a plate tying the shock tow to the roll cage. However, in this structural design, all of the strength is being concentrated directly at the point of concern and gives at least to us, a fairly cleaner hidden look.
