I bought a set of 5k governor springs for my 97 P-pump from DDP. In the instructions it stated that I needed to reuse a couple of shims. My pump already had 4k springs in it, so there are no shims in the pump. I contacted them 3 times over a 4 day period with no call back from the person who was supposed to know what I should do. What is the deal with this company?? Does any body know how thick these shims are, and if they are really needed? (and if so where can I get them?) I dont mean to call a vender out,but damn. It would more than likely only be a 20sec conversation!*bdh*
