1962 GMC K1000 front leaf spring leaf length?

[Ledslinger]

My 1962 GMC K1000 Suburban has different length bottom short leaves on the front springs. Second shortest on both sides is 21-1/2". Bottom leaf on drivers side is 19-3/4", passenger side is 13"

The odd thing is the bottom leaf on the driver side has an imprint on the bottom from an 11" spring, which either means there was 6 leaves originally and the last was removed, or this leaf was installed replacing the original maybe 13" leaf.

Maybe it sagged a bit on the drivers side and the 13" leaf was replaced with a longer stiffer one to level the truck. Though this seems a bit odd that anyone would notice and then go through the trouble to fix it.

How many leaves and how long are the bottom two on your K1000 or K10? Are they usually the same on both sides?
