There is no easy bypass on those engines. The engines without AC had an idler in place of the compressor. The problem is that there were not a lot of them without AC so the OE brackets are scarce. However there is an aftermarket item that will do what you need Dorman part number 34152 bolts in place of the AC compressor and you run the same belt as it already has. What is the issue with the AC on the truck?
