Here is a photo of two sets of dash brackets.
Are the ones in the middle earlier ones?
Are the backs of middle ones solid or hollowed out?
Herb,The middle ones are the 09/10 style with the countersunk holes to take a countersunk slotted machine screw. A rare find! I am looking for a pair the same as the outside ones for my sons 1916 project if those are avaialalble?
The middle ones are hollowed out.
Herb..all I can say is the backs of the brackets on my '12 are hollowed out, just put them back on two days ago after I got my newly rebuilt engine put back in. So using that simple logic, I would say the middle ones are early.
