Gonna have to take look at master cylinder that's on the car and try to see what date code it is. One of them is original to the car.

Not withstanding the date code being Dec 65, appears the inner brass component could be replaced along with correct brass adapters would make it identical to an early 65 unit?
Assume without the adapters, the hard lines with flair on end would mate to the internal brass fitting?
Seems difference between 65 and early 66 is the presence of the adapter.

Thanks Jeff
Guess I assumed the internal brass insert with small hole was a sort of metering device.

Wonder why this master cylinder has the small internal brass piece in one port and nothing in the other one?
Assume the external adapter has pipe thread on the end that goes in the master cylinder and a flare fitting on the other end?

Thanks Jeff
If julian date is 3 digit number, how do I determine which year it really is?
I see "342" on one side and I really can't determine what numbers are on other side.

Here are pictures of my master cylinder. Appears one port has a brass internal orifice and the other port doesn't.
Would 5S228 have the brass adapters or not?

I looked at the master cyl and it has same casting number B2225032 with what appears to be "342" where your example has "357".
I think one I am looking at was original to 5S228, but may be mistaken. As Bob indicated, 65 and early 66 both ports on the Master cylinder have a brass adapter to transition from the pipe thread to flare fitting of the brake lines. Master cyl I am looking at does not have the brass adapter fittings. So I am not sure what I am really looking at.

On lower front of master cylinder are two ports. Front most port goes to the M port on the proportioning valve and on to the rear hubs thru the R port and the other port on the bottom, goes to the block that routes fluid to front right and front left calipers. Of the 2 ports on the master cylinder, the front one that goes to the proportioning valve has a much larger passageway for fluid to travel versus the lower port that seems to have a sort of brass restrictor in the cylinder where hard line connects. Is the small brass appearing fitting with the small hole in it correct?
Would think lot more fluid would be pushed to the front port with out any restriction versus the lower port with the much smaller hole for fluid to pass to the front calipers....

Am I correct that the proportioning valve only affects pressure to the rear drum brakes and has no effect on front calipers?

Will send it up to Jim C to waive his magic wand over.

Is there a date code on the 65 GT350 Master Cylinder? Believe it is stamped/cast B2225032 on bottom.
Thanks

If the rubber band/gasket is really old and clearly cracked, assuming brake fluid would come out?
Thanks!

On the outside of a 65 K/H Proportioning Valve, there is a machined groove which has a rubber grommet in it. What function does the rubber have?

Guess the inner fender SA plate goes with the car?

Pucker factor has got to be high when it rolls on the truck and when it rolls off.
