I guess that it is normal to find odd things in restoring old trucks, and here is one on mine. The front leaf springs on my Chevy 54 3/4 ton have 2 more leafs on the driver's side than on the passenger's side, 10 vs 8 including a base plate. I'm curious as to how many they are supposed to have. My guess is that the drivers side was replaced, maybe someone was psychic and knew that a future driver was going to be a bit heavier than he should be. This has to have been a farm truck for part of its life as functionality was clearly more important than looks. There are three sets of rear lights, when one set failed another would be installed leaving the old ones in place.
You should have 8. Not a bad idea though having more to compensate for the Dunlap disease (my belly dunlap over my belt!)
Farm Fixin' It might have been they used whatever they had at hand or could find...... In my youth we fixed things however we could , lotta bodge - jobs on the farm .
Thanks for the information. I was thinking that the shorter leaf stack was probably right as it more matched the rear springs. I had a great summer in high school one year fixing up an old sickle mower, hay rake, and hay baler with its own small engine. They were a good match to our decrepit old IH tractor. It is amazing what you can do with baling twine and wire.
