Source for Stock? Brakes

I have a 1967 Barracuda 383 FS, converted to 4.5" BP 10"x2" rear drums and 4.5" BP slotted front rotors (I did not do the conversion). Now, we all know the stock discs are solid rotors and had the small BP, what I'm dealing with here is; I want to replace my rear wheel cylinders and front wheel bearings along with new rear shoes and front pads. The rotors seem to be in very good condition but I'm not opposed to replacing them too. Caliper part number I think is 3898*962 rear wheel cylinder PN 29477 C below that is G 23. Does anybody recognize any of these parts or numbers. sorry to be long winded on this.
