Thank you.

My '69 Chevrolet P&A lists the R/F brake caliper assembly as part #5469123 and the L/F brake caliper assembly as part #5469122.

Thanks again.

Right front part number 5463633
Left front part number 5463833

I did not look for a date code when I wrote those numbers down 4 years ago.

Post by: camaro cat on October 12, 2009, 12:33:05 AM: Are you sure that's right? I looked at mine and they are both cast 5463633. In looking at them they are the same casting, just machined differently. I noticed that on both, the first 3 digits "546" are the same size. On one the number 3 in the 4 spot is a much larger font that any of the other number's, but on the other caliper it is the same size as the first 3. On both, the last 3 digits "633" are larger font than the first 3 or 4. The caliper machined for the passenger side which has the large 3 has a casting date of 20 while the other side has a date of 345. They go on a 02D car. This may be the craziest bit of detail I have ever posted about but to much is better than not enough.

Post by: camaro cat on October 12, 2009, 01:56:58 AM: I understand. I was afraid I had done the same thing and had to go back and recheck. That's when I went crazy and noticed the different styles of font on the numerals.

Post by: sftibbs on October 14, 2009, 10:16:56 PM: The casting numbers on mine are the same as Loren's, except the casting dates are 305, and on the other, 292.

What was the original color of the calipers?
