I don't see any value in a foundry casting number

You just look up the Vehicle Application for a caliper

Unless your buying one new from a dealer,they are recycled
& rebuilt & have all sorts of different numbers on them,that
is of no value at all

The weight of a caliper would push the shipping cost up

Just get a caliper from a local auto parts store

They may be asking you for the GM build spec or brake option code
That used to be in the glove box & lots of info is on the door pillar
label,but you need the service manual to decode it

Maybe you could go to a Dealers Parts Dept with your VIN #
Don't order or buy anything there,just run your VIN # & get
whatever info that company is asking you for

You have to know what your being asked & you don't

None of it makes any sense to me,maybe when you tell
us- I will learn something after 50 plus years.

Front right = OEM Part Number(s): 12497784, 8124977840, 8888924790, 88892479, 8889669860, 88964426, 88964429, 88966985, 88966986

Rear right = OEM Part Number(s): 8889357780, 8889358060, 8890271780, 8890271810, 88935778, 88935806, 89027178, 89027181

You'll need to follow the GM / OEM part numbers as above - and not the part casting numbers.

Try these on-line resources for the replacement parts: www.autopartswarehouse.com, www.partsgeek.com, www.rockauto.com, www.partstrain.com - to list a few.

For example, they (RockAuto) list the replacement brake calipers from around $32.00 each for your vehicle.
