This is the GEARHEADS 605 Conversion Box the gentleman is describing allows one to install integral power steering on an early FORD that used the Saginaw external assist before. I have heard of another complaint but the poster would not go into detail.
Before you blame the box, I would check idler arm bearings (these are a pain and many use later arms with integral brngs) and maybe double check caster settings.
You may want to disconnect the drag link from the pitman arm to check for any binding in the box itself. Did they recommend a Saginaw pump or just the adjustment valve?
Did you perform the required 58 steering column upgrade?
You may have to go so far as to follow the procedure outlined in a shop manual as to mounting special pressure gauges to the system to see if the hydraulics are working properly.
Their not responding has me worried as a friend wants this conversion on his CUSTOM 300.
Please keep us informed.
