If you mean the home made offset in the side sheet to give the rear driver more clearance, that's very common on those old soaks. #20 has that as well. I forget if #346 does. Since it's in a flat, stayed surface, it isn't too difficult to make the calculations work out, but they sure have a Rube Goldburg look to them.
