Default saftey washer part number needed for MA4-5

I have a MA4-5 carb and I need to purchase the copper saftey washer that locks the inlet strainer assembly. I have a Service manual that shows an exploded view of the parts but no part numbers. Anyone know the part number or have a parts list?

Any help appreciated.

Is it #54 on this page? It's the only part in my manual that says "safety washer". If so, the manual I have says the part number is A78-121.

The ACS p/n is "MC16-A48". Works fine. I just replaced mine last week during my annual condition inspection.

In that case noelf has it. My OH manual says that part number is A16-A48. Looks like the ACS MC16-A48 is the same thing.

Also, there was a recent "Tips for Homebuilders" video on EAA's website that shows how to remove, clean, and reinstall the finger screen. A new lock gasket is used and torqued. The torque value stated in the video is twice the value given in the actual Marvel-Schebler service documentation.
