Rockauto lists it as RAYBESTOS MC36239 {#2536239} Professional Grade; New; Bore Size=1" Alternate/OEM Part Number(s): 2536239 or ACDELCO 18M1027 {#19106813} Alternate/OEM Part Number(s): 19106813 https://www.rockauto.com/en/catalog/...+cylinder,1836 (click on "info") Pretty sure Drum/Drum, Disk/Drum would use the same one.

Re: 68 Master Cylinder Part Number
Thanks LockDoc
I'm shopping online for it and there are so many that claim to fit. I want to narrow it down. |

Re: 68 Master Cylinder Part Number
The only difference between the disc and drum may be piston diameter and the proportioning valve for the discs. Rock Auto has always been pretty accurate for parts for me. My local ABC another story. Got a box of stuff to return today. Drum/drum is most likely the 1" piston on a 1/2 ton truck.
