Number of leafs

[cuda]

My '87 K10 sits a little high in the back; or maybe low in the front, although I'm pretty sure it's the back. Anyway, the spring pack in the rear has 4 leafs + 2 thick overload springs. From searching posts here, I've never seen anyone say that 2 helper springs are stock, only 4+1, 6+1,...stuff like that. I'm not completely ruling out the front leafs (3 or 4 leafs, can't remember now) because they looked pretty flat and dearched, if not somewhat recurved. Thoughts? Does it sound like someone slipped an extra helper in there? If I can figure how to post pictures here, I'll try to snap some in the next couple of days. Thanks, guys.
