Hey Bill, I was waiting for that one! Ha that's probably the solution though. My neighbor up at the cabin (a 35 year full time chevy mechanic) who's been doing all the mechanical for me, said it's somewhat of a mystery to him. Last week he installed all new gas lines, and said he had not seen tanks like that on any of the old cars he's worked on. They are not rectangular tanks, but are each more a rounded "L" shape and fit into each other perfectly. Then, the original owner had a full skid plate under both that is welded as part of the trailer hitch. Pretty rugged setup, but put together well for those hunting trips. With the low gear ratios, I can't imagine how long it took him to drive the Burb to Alaska. Haven't had it on the highway yet, but think It'll be lucky to hit 60. I'll know in a couple of weeks!
