I just looked and the Kragen On Line price was $22.99.
http://www.partsamerica.com/ProductDetail.aspx?MfrCode=MON&MfrPartNumber=5826&PartType=50&PTSet=AI say this "at your own risk," but I am running sedan shocks on my wagon (1973 if it matters). On the top I used as many shock washers (2 or 3) as one can manage on the shock side and still tighten the nut. I then used a spacer of about 3/4" on the threaded shaft at the bottom (on the shock side as well). Again, that was all I could add and still tighten the nut.
What this effectively did was compensate for 1" the 1-1/2" of length missing from the sedan shock. I've had them in this configuration for a number of months now and have not had any issues of bottoming out or hyperextention
. If I recall correctly in my testing it wasn't compression, but extension that was the issue. Since I'm not too incline to "fly" like the General Lee I'm not too worried about the missing 1/2" on extention.
Again, "at your own risk."
