I think I'm getting some kind of exhaust leak in the cabin of my '71 Jimmy with double wall top. I'm pretty sure the headers and collectors are tight. Could the fumes be coming in from the tailgate or under the truck?
On cold days when it's all buttoned up, I get groggy. On long drives this is bad.
