Tim, I see you have a 66-E. Nice truck. I do understand your question with the dual distributor set up. It’s a complicated system and if you have lots of years under your belt, I would only rate it as terribly difficult! Often a 37 66-E has had lots of changes and upgrades done over the years. You only need one set of plugs to run the truck. If it were mine I would find a V-12 mag and change it over to that set up. They are rare but I do see them once in a while. I thought it would be cool to have a mag on a street car just to mess with some of the members. Hey……it IS factory! I have helped several fire truck owners over the years with the dual distributor set up. Post a few photos of the distributors you are running, as most members have not seen them. My best, Ed
