i have one steering stop bolt that has since left the building, so i
rub at fullturn one way, other is fine....anyone know what size bolt
this is?  i know i need a nut to replace the welded on nut on the
original part, but without taking the one bolt out...i'm going to try
this tonight, but i know it's been in there for awhile, and i don't
think soaking it in PB is going to help much (already doing that for a
few days)

so anyone know the right size bolt?  is it metric?  5/16 is too small,
3/8 is too big, so i'm thinking metric...and how long? 1 1/2 inch?
