Willys Jeep Parts Tech:
No, you're going to want to use item #A557; https://www.kaiserwillys.com/master-cylinder-brass-outlet-fitting-2-port-fits-41-66-jeep-willys Thanks

This fitting is exactly the same as would be used on a 1940 Packard, except both fittings would be 1/4 inch. Anyway you'd be be willing to make me one like that?

Willys Jeep Parts Tech:
Sorry, I dont have a listing for something like that.

I have replaced the master cylinder and all the master cylinder outlet parts: Y fitting, outlet bolt and both washers twice. It continues to leak at the Y fitting when I try to pump up pressure to start bleeding system. Is there some trick to this I'm missing?

Willys Jeep Parts Tech:
Make sure everything is tight and you have the crush washers installed.
