EvenX82,
I did a quick search on "duckduckgo" search engine (one of the few that does not track your information and searches) using "1946 Chevy COE".
Came back with a variety of results, with most of people selling entire trucks and not just cabs. Found in various conditions (restored, un-restored, modified) in the states of Louisiana, Missouri, Wisconsin, Minnesota, Arizona, Idaho etc. Best bet may be to find/acquire such a truck and part remainder to help with the cost (if that is a concern). I will keep my eyes peeled for you as I regularly search the web for things our community may need/want.
Good luck in your search!
