Does anyone know the difference between 1911/12 and 1913/14 firewall brackets. In particular the markings on the bracket, are they part numbers or dates.
The ones have viewed on vehicles are not consistent from the left to the right. Cannot find anything in Bruce’s Book. Would any have any information on this.
Thanks Michael A.

My 1912 has firewall brackets with larger embossed factory numbers. Most I see are like yous. Don't know the dates.
