Topic: 65 SJ C code Differential Paint Marks - Need Help

[CharlesTurner]

My numbers are the same as Chris: C4ZA 5556 N 282 E 4. The dots are green. I know that our cars are built within a few weeks apart in San Jose.

FYI... don't know if we discussed on this site, but the 282 is the day of the year.... 4 would be 1964.  Not sure what E means, but it shows up on multiple year leaf springs.

The 282nd day of the year would of been October 9th back in 1964. Interesting

Just an F.Y.I.  I restored a 66 Shelby carryover car a few years back, was built Aug. 10, '65 at SJ.  It had pink paint on the top (as installed in the car) of all 4 "U" bolts.  I know the build date was accurate, because I found a quality control line card under the original carpet, passenger front floor. 

Hope this helps to add evidence to a possible pattern.

I found some new marks on the differential today, any ideas what these would be? The check mark looking marks are on the driver side, the number on the passenger.

 My 66 coupe has the 610lb. springs with c4za-m number and 2 white stripes on them. Bill.

Always more difficult to tell from pictures but here is a shot - You'll have to confirm in person.

Passenger end looks like a "2" (upside down) and yes a check mark or a poorly finished "X". "2" in yellow and the check in white ? Possibly a secondary (on first) pink line under the bottom edge of the "2"









Drivers side  looks like a number "14"

Thanks Jeff, I'll keep up the investigation while I get it cleaned up.

Not sure if you have seen it in earlier post but, if your removing everything. if you spray some oven cleaner on the marks that will expand and highlight as they dissolve. Take a picture or two of them during the process since they go away fairly quickly at that point

Just a thought
