Won't be much help, but down here in Aus, at a recent Kustom Nats, one of the Countries leading kustomisers, chopped, 2 doored, and Sectioned an FX Holden, (sorta looks similar to a late 40's chev, if you squint a little) during the course of the weekend, it' would'a been a great way to see how it all happens. Won't be much use to you though.

Hope you recover shortly
