SM465 Reverse Light Switch Gasket?

Does the reverse lamp switch need a gasket on the sm465? Im replacing the switch and it’s hard to tell if the old one had a gasket or it’s just old paint.

If it does need a gasket where can I get one? I can’t seem to locate one.

Just purchase a thin oil plug gasket and call it good.

Thanks for the part number. That lead me to this thread so I purchased Dorman 970827CD washers. Once they arrive i'll report back to confirm they fit.

I have several transmission switches with washers. If you are willing to post the dimensions I can see if what I have is the same size.
