Where can I buy a master cylinder cap?

[sgms18]

I need an extra cap for my power bleeder. Can the cap be had independent of the master cylinder? Apparently there are two sizes. The cap i kept to use is the small one & of course my new master cylinder is the big one. I've had no luck finding one so far. If anyone can point me in the right direction it would be much appreciated.

And the mystery source is ?
Part Number ?

No part# that I know of. The nice lady at Southeastern in Augusta GA went in the warehouse & pulled the cap off a new MC believe it or not.

Are the m/c s the same part # whether they have the small or large cap ? If different, any chance you could find out what m/c part # they took the cap from ?

The part # for my new MC is 7539267 & it has the larg dia cap. I don't know the part # for the old MC I took off but it used the small dia cap & had the 2 extra ports on the sides pluged w/bolts & copper washers.

Added the necessary valves and fittings for me to bleed the brakes easy and the length of hose and sightglass volume became a reservoir. Anyhow I liked watching the fluid level go up and down in the glass. It is an at all times visual no leaks, leak check. The very top of the sight glass is vented.
and in no particular order is pictures for the general.

It is all Swagelok fittings and hoses.

Removal of the little soft metal anti surge plate is a must do. Reasons in the PDF.
