Are Original Calipers Date-Coded?

I upgraded my disc brakes to Wilwood two-piston calipers but got to thinking...since my car is a X66 SS396, could my calipers I removed be original? On one caliper there are two cast numbers on it. On the piston area it has an "A" and below that it has; "F8C12" (December of 68?). That would be perfect as my car was built in December 1968. Underneath that is a larger "510" cast into it.

Yes, they're date coded. Check out Camaros.Org or just search on this site. The pics here might be gone, I don't know, but the ones on .org are still there. I'd post a pic of mine, but it's a 69 and different from yours.

I looked on the CRG website, but could not locate any date code info on the calipers. It does say that the J50 option was included on SS396 cars, but that's all the info I found.

I wish I could help you, but normally I'm used to seeing a Julian date. What you posted is obviously a date code, so I'm not sure. Someone will be along that can explain yours. Good luck and Happy New Year.

My '67 4-piston calibers use the Julian date codes.

I guess that could mean that these aren't original then.

I thought original Camaro calipers were "633" not "510". When I was Researching this I found conflicting info with date codes etc. Many guys mistakingly used the casting #.
