Found another winch to my second OC-3, its a Carco model S, see picture. Seller also had a swedish made dozer blade. It is outside trac frame mounted so one does not have to worry about nose diving. I know the trac frame is to weak for this kind of blade set up but for my type of driving it will be perfect. I'll post a photo of it tomorrow.

Here is the blade and outside tracframe fixture.
