Van cab - body connection

[garths]

I am painting a 1971 van and have removed the the van box from the cab to facilitate repairs. Unfortunately that was 6 years ago and i can't remember how the the hood lining in the cab and the wood packer pieces are configured with the pinch bolt heads to achieve a neat result when bolting it back together. Can anyone help? Pictures or diagrams would be good. Even recommend a reference manual or book that is available.

Thanks
