[Mgs] Manual washer pump nut

[Larry Daniels]

I need a retaining nut for a manual w/s washer pump Moss part number 361-160.
This would have been standard on a 1098 Spridget or a 62 - 67 MGB.  It has a
weird thread that seems to be either 27tpi or 0.95 in metric and is about 5/8
diameter.  The pump works great but the cheap plastic nut broke and can't be
matched at the local hardware store.  Anybody have one laying around in their
misc. parts drawer?

Thanks,

Larry
