I believe that the short answer is probably "no". As indicated above, if you are referencing 1929 "open car" doors (roadster, phaeton, roadster pickup), then the front doors are all interchangeable. However, closed car doors are another matter altogether. Murray and Briggs fordor bodies have different width doors, and regardless, I believe would each be wider than open car doors. Similarly, I also believe that coupe and tudor model closed car doors would be somewhat wider as well. Hope this may help.
