Be advised that the 49-51 Ford used special wrenches to adjust castor and camber. There happens to be an NOS caster wrench for sale on Ebay. It is under KR Wilson the listing is for a 3089-N wrench. I was able to make my own by looking at the pictures in the service manual but have since purchased a 3089-N and am looking for the camber wrench which is 3046-N. My experience is that most alignment shops do not have the tools to make the proper adjustment. . . Chuck
