Had an annoying issue with modern version of the worm gear style screw clamps on my Hurst.
New ones are so flimsy compared to what they used to be, and my original Corbins aren't cutting it anymore after 56 years. One actually broke and the other had lost tension enough to leak slightly.
The new worm style fall apart under the slightest tightening compared to old versions, and if you are successful in tightening without stripping out, they either stretch or slip when the engine heats up and then leak after things cool down. There is a version available at NAPA that is really good, but it's a hose clamp that sells for $12! Guess I'm getting old, but that sounds crazy for a hose clamp. I may start removing clamps off of old cars in the junk yards. ;-)
