firewall markings
First is a big M behind the brake master, 2nd is a 1/4th looking mark behind the engine, above that is the numbers 269.
Also stamped on the firewall is 5 17 2A ?
not sure what they are for? I would guess the M is for color, here are some pic's if that helps
Thanks for helping me understand what they mean.

I'm just picking at you Bill, how's your weekend going?
the 517 2A is the sheet metal date stamp code...I THINK 517 is either 5= 1965, 17= 17th day of the year or month... 2A...2nd week of month, A= 1st shift ...Its just a guess mind you...Im hunting for info decoding the date code of the sheetmetal and other parts.
I did see a bit online where the Jan 92 issue of Mustang Monthly has an article on this on pg pg 26 as I recall it saying...
