Some caps are vented, some not. My memory is fuzzy on these, and I didn’t mark them when I pulled them. Brake vs clutch, or production date difference?

Mark, both brake and clutch are vented (little cap retained by a small cotter pin) on my early '64. Difference may be production based.
Mark lwt me know if your gonna have a box of these up for sale. I may need 1 or 2. Thanks Mike
It was a production date thing. I think the vents started in 64.
'63 FJ45 clutch and brake master cups - no vent but rust included (and both are Tango Uniform). And that spark plug thingy is top secret, need-to-know so don't ask.
'65 FJ40 clutch master cup - vented (brake master cup is plasticized)
(65 + 63) ÷ 2 = 64. I guess that settles it, LOL. Ok, Splangy knows way more about this stuff anyhow, so follow his answer, 64!

We will talk.
And if anyone needs one of these tubes, apparently I have a baker’s dozen
Those are the large diameter clutch tubes, yes?

Yes, but, I need to do a little more sorting. Before I left to come home I saw another one attached to a 69, which reminded me of the difference between the ‘direct’ ones and the banjo ones.
Info... notice the large tube from the clutch master, this pin points the clutch, brake has the smaller 9 mm fitting.
Info... notice the little hole in the photo of the square cap on the brake master cylinder, that would be your vent.

My 64 build date fj40 has non vented caps.
might check again...one of mine looked non vented, but had a pin hole in it
Interesting. I'll have to see.
My 5/63 build had/has the caps with the hatted vents.
Here is my 65 FJ40 with a early 64 build date:
View media item 44438 From a July 1964 FJ45
My '66 has the vents.
My Jan '66 does not
no hat, but looks like the brake master has a hole drilled in the side of the square plug for a vent.
looks like the one in @middlecalf pic above

Good eye. Had to go out and double check but it does.
