1983 Dodge 400 Coupe with Manual Transmission Production?

Hey, this is Sam, and I am the proud owner of a 1983 Dodge 400 Coupe with a manual transmission. I've come to learn that the manual transmission is very rare, to the point that I can find little evidence of it being made available (The Dodge 400 wikipedia page lists it as only being available in the three speed automatic). I dug up an article mentioning it being released to a few select dealerships in the manual as a test, although as we all know canned the 400 in 1983. The only other evidence exists in the only Dodge 400 commercial, which features my almost exact vehicle driving on the beach, with a manual trans.

What I REALLY want to find are the production numbers for Dodge 400's with a manual transmission. Do any of you know how I'd go about finding that? It seems the Chrysler website allows for a request of build record, but not much else. I'd really like to know how many of these were produced in the first place, as I haven't been able to find existence of another one. Thanks!
