The International Cessna 170 Association

I'm looking for some hardware for the center window support strap. The IPC shows the following part numbers: washer is 0311001-27 and cap nut is 22NKM-10-3. Does anyone have a source for these or have these been superseded?

Thanks,
Doug

Doug,
Those washers, made from cork, are used in several locations on the 170. I wrote about them here and again here. Superseding Cessna p/n is S350.

The bubble top nuts are described by Genuine Aircraft Hardware here. If you're an originality nut, the nut to get is one without the Cad II plating. Delete the "F" in the part number to get silver Cad I plating. They can be ordered from this page of Genuine Aircraft Hardware's website.

I've ordered the nuts and washers. Preferred Air Parts had the best prices for S350 and 22NKM02.

Thanks again for the help!
