I have spoken with Heidts and TCI, and seen a detailed response from Fat Man regarding the ball joint issue. While I could get into the physics and mechanics of it all, the bottom line is the combination of parts they produce are tested to be strong and safe, and have proven so with many 10s of thousands of these in use for decades. Regarding the weight capacity, I agree that OEM Mustang II parts are too light for many street rods. The new, aftermarket parts, however, are much stronger and can easily handle the weight of a '34 Chevy pickup. At our shop, we have NEVER seen a failure as mentioned above, and I would not hesitate to use any of these Mustang II systems.
