Master cylinder

[Jerryl]

Last year I replaced the Hydro boost power assist unit and rebuild the master cylinder. The cylinder had some minor scoring and, was suspect. After honing it, it worked fine ..... At least for a few months.

At the time, I was unable to find a replacement unit. Now I need a master cylinder.
Anyone know where to locate one or if another GM unit will fit?

Hey Jerryl

Not sure on GM.
When I replaced mine, picked one up at Oreilly's or Autozone.

Bob,
Found one at Napa today.
Looks like the box was about 10 years old so, it is an original replacement.
Neither Autozone or O'Reily was able to get one.

Thanks!
