OK guys. I checked with chevy's of the 40s and they don't have the tools. Plus they aren't local to me anyway. I checked a couple local machine shops in the Kansas City area that have rebuilt these engines and they didn't even know they were adjustable. They both said they have never adjusted them. So far I'm striking out as far as getting them adjusted. I'm tempted to repair my old pan and just assume it's adjusted correctly. I even contacted Jim Carter and he didn't know where to tell me to go. Any more ideas?
