So everything I have found on the internet led me to an S522 wrist pin from Weisco as the proper part for my 1984 ATC200M. Upon arrival, the new pin is much longer and although the O.D. is correct, the new pin is much thinner (I.D. is larger). See the picture I have attached. As you can see by my old pins condition, I would hate to re-use this. Any help is greatly appreciated!
