HELP! Can anyone ID these marks on my calipers and spindle???

[Zaz Beam]

Has anyone seen these marks and know what they mean?

I bought a GM A body that have these B body spindles and I'm having trouble ID'ing them...need to replace rotors and calipers but don't know what I have. I think they're GM metric...maybe from a monte carlo or malibu?

Thanks

I do believe those are the time they were cast.

Yup those are the time stamps for the casting. Not PN#. Attach a picture of the front of the caliper and the pad.

Deciphering what your wrote. Does this mean that someone previously installed B-body Caprice/Impala spindles on your A/G body? To get the 12" brakes? This was a popular swap in the 1990s before the S10 Blazer spindle conversion came along.

If this is the case, then you need to find 89-92 the Camaro '1LE' rotors. RockAuto has a couple to choose from. Here are some tech pages so you can measure your rotor diameter to check if I am right or wrong.

Thank you everyone. To be clear I am not sure of what kind of B body spindles I have (1969 Buick Gs400 convertible- has full umi/viking suspension sans the spindles) but my guess is that they are metric b body...i guess this bc of the matching pics I've found online.

Here are a few pics of my rotor/spindle

I attached pics of rotor and caliper. Thank you so much for taking a look.

Time? From that mark with the dots? Then why dont you see that on all or even more GM calipers and spindles?

What are they using, a sun dial?

It's easiest to put on there and small. The first one was cast at 10 (am or pm), the second was cast on 12 (am or pm) shift.

That's actually what it's for, when you're on the side of the road changing a tire you can see what time it is.
