Front leaf mount bolts

[Pender1]

Anybody have diameters and lengths of the stock leaf spring mounting bolts for a '84 k10? I see 7/16" and 9/16" thrown around, but not sure. Don't have my truck accessible to check right now.

There are two different sizes... The 7/16 is for the rear the 9/16 is for the front.

Thanks, any idea what length they are? I think it's a 2.5" leaf, so would 3.5" work?

No clue. Measure width of the leafs and add a bit extra. You need 2 washers and a nut so take that into account.
