Does anyone know where I can find the production numbers for my 1977 Dodge Macho, Short Bed, silver/black, 440, skylight truck?

There was a fire in the late late seventies, early eighties in the Chyrsler Records Building and those records are gone...........In 1978 Dodge sold the most trucks. There were only 71-79 440s installed the D-W100-150 chassis. I would suspect a slightly higher amount of 440s in the '77 production year.

Thanks
