wiper motor gasket?

[Rod Run]

A bit of a dumb question here, but I'm going to ask it anyway.

I'm putting in my wiper motor, but don't have a gasket. I'm not going to spend more in shipping, than the gasket it worth, so what have you all done for ideas with your gaskets?

I know there must be a few different ideas out there, so I'd love to hear them.

Thanks
