Great information.


 I used regular (sedan) Pinto shocks on my wagon. Because the threaded portion is so long I was able to slide a thick wall tube over it. Ironically the early Pinto's have a similar pin type mount on the shock top as on the bottom, not the crossbar type in your picture. Lacking additional thick wall tubing I then stacked extra cupped washers on the top end to place the shock closer to its "travel range." So, either way the thick wall tubing, or stacked washers, you get the same results because the spacing places the shock very near its normal operating position. I was able to compensate for 1-1/2" of the 2" difference in the shocks. Note I did this to the "inside" sections.  6+ years and so far so good. But I do caution that one does this "at their own risk."
