My 65 cuda is mostly a purpose built drag car that is street legal. Some rules changed in KOS and inner fenders were no longer required. Already had a custom chrome moly tube k member with coilovers and rack, which is light years better handling than stock. But, when the inner fenders were removed the front got flemsy. Then removed the radiator support, including lower support. Thank goodness the k-member is welded in. This stamped sheet metal mentioned earlier in this thread is a huge part of rigidity in your front suspensions.
