I don't see a lot of light duty 3/4 tons but I would say the bottom spring is thicker and longer looking than any 1500 I see. (I personally wouldn't call the bottom spring an "overload" but it's all semantics). My 1995 GMC k1500 ecsb with F44 did not have 4+1 rear leaves. Only 3+1
About 15 years ago, I was talking to a guy who had a 1998 K1500 ecsb parked at my office. He said "it was the same as the 3/4 ton". I said no because the gvwr will be 6600. He opened the door and I'll be damned but the sticker inside the door said 7200 gvwr but it was definitely a 1500 with the 9.5 rear end.
It's interesting that someone found a light duty 2500 with factory 4.10 gears. I didn't think that existed.
