Marc, You are right of course. I wasn’t very descriptive in calling it an offset bracket. But… isn’t the cooler itself the same? ie., the same old 1500 cooler with a new mounting bracket that has internal passages instead of mounting directly to the top of the case? The result being that the cooler is moved a few inches forward, out of the direct air path to #3&4 cyl so in effect the “doghouse cooler” becomes and external oil cooler? I thought that I could use my existing cooler?? Or would I have to buy another cooler also. (This is exactly where I am on rebuilding my 1500 engine. I am about to put MiGi’s fan shroud on and wondering if I should spring for a doghouse cooler, big fan and associated tin work. This project is running over budget and retired $$ age harden and don’t stretch as well as they used to.)
