I'm trying to get a tap for the rear petrol tank lugs on a WM20, and don't know what size it is. I believe it is a 26TPI, but don't know the diameter. Does anyone know off hand?

These are the large shouldered bolts that fit vertically through lug holes in the frame and screw into threaded lugs on the rear of the tank.

Thanks,

Kevin

Just double-checked one and it is 5/16" x 26TPI .

Thanks Ray! I appreciate the answer.

Mine also has a thru hole in the bolt head for retaining wire. as no wire was in the bolts when I removed, where should the wire attach to?
