I have a 64 cuda that has a 4 speed drive train from a 69 GTS to include the 340. I'm in the process of gutting it and I noticed that I have a bunch of stress cracks/tears where the tunnel meets the hump for the rear axle, basicly where the pinion snubber(?) is. Also a few random ones further out towards where the seat belts would mount. Anyone with ideas as to why this has happened. No evidence of a prior crash. Pete
