What are the dimensions on these springs? The length & bolt sizes where they mount to shackle & frame? Thanks.

They are 52" long for 1/2 ton, 56" for 3/4 and 1 ton. I believe the bolt diameters are 7/16.

I remember reading somewhere that *some* 3/4 tons came with the shorter 52" springs. Can anyone confirm?

Actually, I have 1/2 ton trucks with 56" springs. One short and a long bed.

no real pattern from what i have found, besides the 1 tons seem to always be 56. But as far as the rest i might depend on where the truck was built?

Yep. My K20 Suburban has the 52" springs. Makes it difficult to find some lift springs that don't leave the rear sagging.
