After spending several hours taking apart the control arms, tie rods, etc from my '65, and a few hours of internet searching, found that I have 73-87 control arms and spindles. The more I dig into this truck, the more things I find aren't original. Since the last owner before me didn't know much about the truck, it's hard to know what all they used. My advise would be to keep a list of donor parts you upgrade to or add along the way in case the next guy or family member knows what parts they'll have to look for if they need to replace any. As for the newer parts on the truck, I have had no problems with the steering or the ride, other than needing new ball joints, tie rods, etc.
