Dwollam,,
definitely round door bottoms on the cowl hinges are definitely inside the bodywork ... just found this post while searching google for an example - doors as shown here
https://forums.aaca.org/topic/282477-fs-pre-1923-dodge-brothers-touring-doors/
on the passengers side of the firewall there is a body number stamped that reads "577007"
a thing I thought odd as well, was the factory screen mount support - where screen posts bolt to- seem to allow a reasonable slope backwards . I always thought the screen was more-or-less vertical ::
any more help to id the cowl would be great ! oh did I mention im looking for screen posts??
thanks
Alex
