Default YS 91 Gaskets?

I was woundering where I could find the backplate gasket for the YS 91 I can seem to find one and the one on my .91 broke when I was replacing the back bearing.

Rick's carries them,
however in an emergency (flame suit on) you can make one out of printer paper. Place backplate inside up on the paper and trace around and mark the center of the screw holes. Turn backplate over carefully center the inside of the backplate over your tracing and mark draw your circle. The rest is done with a hobby knife. I know there are probably a lot of rolling eyes out there but this does work and the gasket will last until you remove the backplate. I've had one in one of my engines for well over a year and it is still hanging in there. I ordered the gasket from Rick's and it's still in my parts box. If you want, PM me your address and I'll mail it to you if you'll send me one when you can.

Ray has them too!
There aren't a lot of places that actually stock YS parts unfortunately, and Great Planes orders when it's convienient to them, not us... go figure.
