How can I find out what my 60 is out of?

[SchnorrCS]

Guy I bought it from had it in a Blazer, and the guy before him did the swap. How can I find out what year make and model truck it came out of, for ordering parts and what not? Also, the 14 FF I got from the same dude has a disc brake conv done. How can I figure out what brake pads/calipers to get? It has calipers on it now, but what if I need to replace them? Any thoughts?

Say it's out of an '85 Chevy K30. Rears probably using 3/4t front calipers and rotors. Post pics.

Not much difference in the GM 60's over the years, and not much variation in the rear disc swap parts either.

Find the BOM number, its on the front of one of the axle tubes (long side I think).

Then compare it to this chart.

I think you can run the Bill Of Material (BOM) number thats stamped into the axle tube. That should give you that date it was made, not sure about what it was in. Obveously it came out of a 1 ton, 1977 (I think) or newer. Unless it's a Dodge D60...then I don't know.

Usually rear disc conversions use late 70's early 80's 3/4 ton Chevy front rotors and calipers/pads. I've seen brackets that were made for late 80's 3/4 ton calipers. The metric (late 80's) casting is a little differnt. The pads should be the same from 73-87, 2/4wheel, 1/2-3/4ton.

As already hinted, all you really need to know for the front D60 is whether it's a Chevy/GM version or not. If it is a Chevy version, then I don't think there is really any parts on it that are year specific. Sure, earlier versions had necked-down inner axles and such but that is all a moot point because non-necked axles are a direct replacement (and better).

Same goes with the rear, just verify what calipers they are. The most common I have seen used a Chevy/GM 3/4 ton front caliper and rotor setup. The biggest difference is knowing whether it's an earlier D44 version that has SAE brake line connections, or a 10-bolt with metric connections. I believe the calipers can interchange with the exception of hooking up the brake line.
