1940 Packard Master Cylinder Kit?

Recommended Posts

Once again, I'm working on a friend's 1940 Packard 120 sedan. 

 

I need to put new seals in the master cylinder.  The piston is in good shape, and I just need the seals. 

 

The cylinder has a one-inch bore with one cup-type seal and one ring-type seal.  Anyone have a source or part number?  I believe the original number might have been 25. 

 

It's really frustrating.  I worked in auto parts for 11 years, and we always had trays of seals.  Those days are gone, and NAPA and Carquest can't even get the ring-type seals at all.  If they have the cup-type seals, they make you buy ten at a time. 

 

Thank you,

JON

If Napa cannot help then both of the primary Packard vendors, Max Merritt  https://www.parts123.com/parts123/yb.dll?parta~dyndetail~Z5Z5Z50000022b~Z5Z5Z51704~P45.00~~~~S5TT0W0ZIH73235120470a~Z5Z5Z5~Z5Z5Z50000022B  and Kanter Auto   https://www.kanter.com/packard/pac-120.html#1 show the 1940 master cylinder repair kits as being available.  These are complete kits though so from the sound of what you describe as needing, probably more pieces or expense than you are looking for.
