The Most Devastating Engineering Miscue Found in Early A-Bodies

clifftt said

Body flex. This Cuda has cracks in the same place on BOTH quarters under the back glass. My first Cuda had the same crack on one side. Too much flex between the front and rear subframes, I suspect. I’ve had frame connectors welded in since then. Hopefully, if I ever repair and repaint this car, this problem stays away.

Thank you for sharing this. I noticed a slight crack on one side prior to my body ('65 Barracuda) going into the paint shop, now I'm concerned about this reoccurring. I did some research on frame connectors and see that USCarTools makes them. I never gave body flex a thought until I read your post, I'm ordering the frame connectors, I'd hate to see these cracks come back after the car is painted. Edit: Found some "before" pictures, its all filled now. I seem to remember the joints had lead in them.
