The Most Devastating Engineering Miscue Found in Early A-Bodies

The suspensions were virtually identical from '62-76. No real upgrades there except for the larger upper ball joint in '73. Frankly, I've never broke the small one, so, I'm not sure what the fuss is all about. To me they should have used the bigger ball joint and brakes just so they would only need to stock one part and not have the extra tooling cost to have several different ones for each body class. Same goes for the 7/16 vs. 1/2" studs. I've never had one break on me driving, but, 1/2" ones would have made things a lot simpler. The SBP wheels never made sense to me, but, at least they were 5 lug instead of 4 that some of their competitors were using. At the least, they should have had the upgrades in '64 when they started the V8's.....especially the brakes and rear ends.
