Part Number Verification

I show a 69-70 Skylark /GS power disc brake car would have a master cylinder:

Group 4.650


Part # 5468120.


I am trying to verify the application for a master cylinder off a 70 GS with

Part number 5468309.

 

Part #

Jim, one of my parts book, shows same 5468120, I don't see the other number anywhere in my books!

 

Neither do I.

 

Looks like a Chevy number according to this.

 

Bummer. Thanks Korrie. I need the 5468120 for a core and they only came on the 69-70 3000 and 4000 series Buick cars with power disc brakes.

 

Per the Cdn. GM parts book:
The original number was 18000996. Superceded by 5468120.
The latter number possibly a common replacement number for any A-body of that year?

 

I think 120 is the correct number . The one I was looking at though was 5468309 which perhaps is a chevy part that came off a 70 GS. It must have have been put on there sometime over the years.
