Default 1951 Pontiac Chieftain Brake Master cylinder Distribution Blocks

Hello,
I have a 1951 Pontiac Chieftain with a straight 8 and I replaced my master cylinder and see that the Banjo Bolt and fitting are bad and have been modified so it still leaks.

Does anyone have a solution for this fix or a place to go for parts?

Thanks for the help...

Curt

Drawing is from a 1935-66 Pontiac Master Parts Catalog.

5450615 is used on other GM cars, including 1953-55 Corvettes. It is listed as "Nut with washer".

799390 is used on other GM cars, including 1953-55 Corvettes. It is listed as "Gasket, outlet pipe and connector bolt (19/32 ID x 13/16 OD - copper)".

799303 is used on other GM cars, including 1953-55 Corvettes. It is listed as "Gasket, outlet pipe and connector bolt (1/2 ID x 13/16 OD - copper)".

I can't find any non-Pontiac listings for the rest of the parts.

Bill,

Thanks for the help, are those part numbers that you have listed in the left?

Any idea who I could check with for NOS parts?

Curt

Look on a T Bird site. They may have one that you can make work

No, the numbers on the right like 5450615 are part numbers.

Check with the facebook group "The Pontiac Chieftain Club". They seem to be quite helpful with finding parts for the flatheads. You can join and post what you need.
