Need part numbers for C15A brakes

[sapper740]

There comes a time in every CMP owners life to do the truck's brakes. Mine has arrived and to no surprise my C15 has C15A brakes. I spent the better part of the afternoon explaining what I needed to pimply-faced kids who's only mechanical experience is installing large resonators on Japanese compact cars. To avoid endless trips to the supply house, does anyone have the part numbers for the wheel cylinders, shoes, and master cylinder? I don't think re-sleeving the wheel cylinders is an option as the first one I pulled is cracked. As you can see from the pic there are some numbers stamped in the cylinder, 3 and below it: S231. Mean anything? I'll get to the passenger side tomorrow to assess it's condition. Thanks, Derek.
