I have a 12 bolt in my 67 camaro. The date code is K208 on the drivers side of the rear end close to the pumpkin (backside of the rear), on the other rear side CN1 is on the rear passenger side, casting number is 3894860N is on the drivers side (backside of the rear).

From what I researched the date code is as follows K = OCT. 20-1968

The rear had factory 4:10 gears posi in it.

Question: does any one know what this rear came out of? Another camaro? Help?

I need to replace the wheel cylinders and auto parts can not seem to be able to identify these. The rear backing plates have "brackets" the cylinders have to fit in between.

I am new here.
Thanks for any help.
