you are getting into completely 'uncharted waters' and an area where running on the road may be unsafe, there may be solutions, but i won't reccomend any of them
the template, as crude as it is, is very simple. you don't even have to have it, just measure from the rear edge of the fender support where it meets the frame (the part that rivits to the frame) use a small square to mark vertical lines. then measure from either the top or bottom of frame as indicated. one bolt will be above the frame and i supply a custom bracket for that. holes are 5/8" except for the hole to clear the adjuster which is 1 1/2"
i am supposed to have lines and pitman arms this week, so except for the elusive reservoir it will be 'ready'
i suggest that anyony who is really going to do this look for your own steering box from international S series, 1975-1990 part number is cast on the back of the box, #7830389
