GM Frame build - Observations and question about cent bolt for leaf springs.

[BrianG]

The bolt that goes through the center of the leaf springs has a round head, not hex shape like a normal bolt would. Sort of like an Allen type of bolt, but I don't think the original ones had a place to put an allen wrench into. I think most aftermarket ones do though. The mount that it sets on should have a round hole where the "bolt" from the leaf spring sets in to.

Sorry I don't have any pictures readily available to show you, but hopefully you understand what I'm trying to explain.
