Also if you are looking at the manual on page 210. the springs look like that except the have the fishhook ends. If it helps, the top left and the lower right, "pin to tab" is 4 3/8" and should have a spring rate of 70#. The top right and lower left "pin to tab" is 4" and should have a spring rate of 90#. As far as application goes. It is a 1959 GMC P303 series or S300. The VIN# is 303PS5674D, 1777 flat cowl, H110 rear end, Eaton SM420 tranny. I submitted some pics to the Gallery, but I am not sure if they posted yet. Thanks guys. GO!!!
