Fibre washer

Hi is anybody willing to help a Scottish fellow mopar man
I am looking for a fibre washasher that sits behind the oil pump and before the front clutch of a 727 torqueflite its .102" thick and sadly the one I have has snapped into three pieces. There is a company that is willing to sell me the part for a very reasonable $2.53 But the carriage is $25.50 for a small part that weighs very little its a bit much tried to source here in the U.K. But everyone over here wants to sell a complete rebuild kit. I rebuilt the gearbox a couple of thousand miles ago must have nicked the washer upon rebuild So if anyone could help me out I would be very grateful.
Thanks Joe
