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

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

Yup those are the time stamps for the casting. Not PN#. Attach a picture of the front of the caliper and the pad.
I attached pics of rotor and caliper. Thank you so much for taking a look.

What are they using, a sun dial?
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.
