As Bob pointed out, in response to Kevin's pictures posted above (which have the same casting numbers as mine), he has the C7 larger hose. Alternatively, is it possible that Kevin's supply line is a repop and the line stamps inaccurately describe the part? I am thoroughly confused and not sure where to start my hunt since I am not exactly sure what I should be looking for. Possibly I am missing something in this thread?
Kevin, would you be willing/able to verify the inlet size on your caliper?
Any additional input, opinions and information would be great!
I'll have to dig them out of storage, but I'll try to get the measurements to you in the next few days.
However, I'm still a little confused as well...
My car was built in San Jose on Sept. 22, 1966 - so I'd say that makes it an "early production" 1967 Mustang. I've owned the car since January 1983, and have service records going back to May 1978 - and there's nothing in the service history to indicate that the calipers were ever replaced prior to me buying the car, so I assumed that the 71312/71315 calipers on my car were the original items that were installed at the factory (there was even a big green paint daub on the driver's side caliper).
However, in response to the photos I posted of my calipers back on March 22, 2015, Bob Gaines indicated that my car had the "later style" calipers, which I interpreted to mean that 1) these weren't the same type of calipers that were being discussed, and 2) my early production car didn't come with them originally (but I still think it did)...
Yes, it's possible that the calipers were replaced at some point prior to May 1978, but could it also be possible that the San Jose plant was using the "later style" calipers as early as mid-Sept. 1966?
Is there anything I should be looking for on the calipers, hoses, etc. that can verify these as original or not?
