4160 carb washer

I need to take a moment to be OCD.
On the Holley 4160 (came stock on my 69 300) there's a brass balance tube with an o-ring and washer on either end. I've come up short one washer when re-assembling and the kits don't come with them anymore. Does anyone have a junk 4160/600cfm carb to pull a washer from so I can re-assemble without flinching?
