(ET) Dozer blade return spring

["SWS" <ssawtelle erols com>]

I can't figure this one out and the microfiche copy on elec-trak.org is one
of the really spotty, faint pages, so:

On the dozer/snow blade, the blade angle adjust (side to side) is done with
the handle. The lever on the handle is used to pull a catch out of a notch
so the blade can be swung. There must be a spring to return the catch back
in place, but mine seems to be missing and I can't figure out where it 
would
go. So can someone enlighten me, please? I'd like where the spring attaches
and any info you can give me on the spring itself.

TIA,
