I'm not positive on the years, but at some point the gear box fittings changed from inverted flare to metric o-ring. If your fittings don't match, then the box or the hoses are not matching. The pressure metric is 18mm, conversely the inverted flare is 11/16" or 17.46mm. Just to give you an idea of which is larger. I believe 1979 was the last year for inverted flare. I wonder if the aftermarket no longer supplies any new or rebuilt Saginaw steering gear boxes with inverted flare fittings. Are your hoses inverted flare or metric o-ring?
