Source for aluminum master cylinder boot?

[adriver]

I'm doing a aluminum master cylinder conversion. Manual disk with the AR Engineering adaptor plate.
And I'm having trouble finding a source for the rubber dust boot .
The master cylinder from Advance doesn't come with one.
I could run without it but would like to find a part number at least.

Help.

That won't work.:shock:
I guess no one uses a boot?
