When these A Models were brand new they had all original parts and pieces. As they aged whatever a poor man could find was what they used to keep them going. I was born in 1942 and rode in my Dad's 1929 Sport Coupe with hand made pick up box in place of rumble seat. Highly likely that there were more modified's than stockers that survived! What ever could be found,modified and used was used. My 1929 Sport coupe has an hand made galvanized sheet metal roof which is laid over the original cloth top. Most likely the rumble seat will be replaced by an hand made pick up bed. I dearly wish my father was around to help me with building that bed...... In my youth we did what we could mostly with nothing and model a's were used by all of us as daily transportation, and we were dang proud to have anything. The wealthy folks bought new cars, us poor folks were survivors. I still till this day like riding in what many refer to as "Depression Cruisers" If you were lucky all four wheels and tires were the same size and brand tire?
So do as you please and leave the new "FaceBook" Mentality to someone else why ask their opinions? I personally don't need others opinions.
