I have a 1955 or 1956 chevy with the napco conversion. It has 3100 emblems on the sides of the cab, but I was told it is a 3600 because the front axle and transfer case have plates on them that say 3600, as well as the wheels having 8 lugs. I am currently looking for a steering knuckle for the driver's side as I broke the one I have when loading it onto a trailer, due to the wheel being locked up. Just trying to figure out exactly what I have so I can get the correct steering knuckle. Any information about the napco drivetrain would help as I'm still pretty new at this. I got the truck just over a year ago.
