1957 Chevrolet 5700 LCF two ton. I have the shop manual for 1957 trucks but of course it has no part number listings. I do not have the assembly manual, for those that have them, is it useful for obtaining part numbers? Specifically I'm looking for rear axle seals, gaskets, etc. The axle on mine is a GM corporate 15000 lb. single speed and in need of pinion seal and gasket numbers. Napa and the local Chevrolet parts don't have a listing but I'm hoping to get a seal number from the current one when I get it apart. Other than measuring I.D., O.D., and depth are there any options for finding a part number?
