Thank you MTFCA. 1 set is sold. Pending payment.
Still one set of 4 for sales
From my research utilizing both the engineering drawings and releases on these, here's how to sorta kinda tell the approximate year (maybe) that they were made. As a general rule, the thicker the truss rod "ears" and runningboard bolt bosses, the earlier the year; however, Ford allowed quite a bit of tolerance in these areas. The late '09-10 truss rod "ears" had a max. thickness of 1/2" and a minimum of 7/16". The '11-'12s were 7/16" and the bolt bosses were 7/16". The early '13 through early '15s were a minimum of 3/8" and a max of 7/16" while most '15s through the remainder of these forgings' production were a minimum of 5/16" and a max. of 3/8". On 2-25-16 the bolt bosses were spec'd at 5/16."
Therefore, due to these wide tolerances, it's entirely possible to have an earlier bracket that is a bit thinner than a later one, and vice versa. About all you can say for sure is, for example, that if you have two brackets, one of which has 7/16" thick "ears", and another with 5/16", the thicker one is definitely earlier. But if you have one that is 13/32" and another that is 3/8", the thinner one could be earlier. Or later. Or both could have been made the same day.
How's that for precision?
One last note on this part: the Ford script was spec'd to be added to the side of the "foot" (where the bolt bosses are) in 1916.
The change to the channel type supports was proposed and first drawn on August 14, 1917, but of course didn't appear until almost three years later.
I think the parts ID books also show that the curves were different, not just the thickness of the boss. (?)
Thanks RV, great information. Mark, the curves are defiantly different on the 1909-10 brackets.
Thanks RV for the info. As I know very easy to change the curve just warmed them with torch flame. I did for my 1911. Brackets still for sales Gentlemen.
Thank You RV !
There is another way to identify the earlier ones, but just how early they are is problematical.
The running board end has the forge flashings on the top and bottom of the bracket, indicating the forging was done with the blank on the side. This results in a bracket with a cross section which is the same either side of the centreline.
The frame end of the earlier brackets was formed with the flashings either side of the bracket, indicating that this end was formed with the bracket in the vertical plane. The cross section at this point is much more pear shaped, wider at the bottom. The three hole foot where the bracket meets the frame is different as a result. The bottom of the triangle is concave on the early brackets, whereas the later style are convex.
RV's observations fit in with this somewhere, but I cannot help with matching those with my observations. I sold the last two early brackets I had at Bendigo swap last year. Both had the early frame end stamping, but the truss rod lugs were quite different in thickness.
