mr48chev your comment about racing application arms is making light bulbs go off above my head. I hadn't heard of racing style arms and the Speedway link you posted looks exactly like the arms I have. I checked another site Southside Performance Machine that has what looks to be the same arm and they list it as "designed for geometry correction" which I guess is another way of saying racing.
In other words that's why these arms aren't giving me the geometry I'm expecting, stock. BTW, the second pic in post 127 is with the engine and cab sitting on the frame. Add the front clip, hood, etc. there'll be more weight but I don't think it will help matters with those upper arms. Another possibility is that the springs are too strong for this old truck application.
May have to go back to stock arms like these to make it all work.
