help ident brake caliper

I just got a 1950 chev pickup and it has a disk brake conversion on the stock solid axle. The truck was in a divorce so couldn't get any info. The left caliper has a casting number of GM54 4839 and the right 54 74338. The mounting pins are about 7 inches apart and the rotors are 11" Any help with what these were used on would be great as I want to replace parts and don't know what year model they are.

Are the caliper hold down bolts a nut head or a allen wrench socket head?

If socket head could be '82 and up Camaro.(metric)

Nut head would be 78 to 82 Camaro.

Standard full size GM calipers are 7.05" from center to center of the mounting bolts and use a D52 brake pad. That sounds like what you have.

What are the threads on the banjo bolt?
What is the thickness of the rotor?

Thanks for the info. Although it is a long round trip to the parts store I took a chance and got calipers for a 70 camaro. They look the same as what I have and will know tomorrow when I go to the shop.
