Replacement oil seals?

I am trying to cross reference oil seal numbers. The machine is a 1972 Nordic 440E. The engine is a type 434.

The parts book says that the mag side is

420 830 400 (402 1138)

PTO side is

420 830 770 (402 1291)

We can usually get seals at the local bearing place (so I am told). Is there any cross reference number I can use so that they will be able to determine the correct size?

I assume those are millimeters? I am curious ... where did you get the information? Is there a resource out on the web with this information?

They are in millimeters. I have a aftermarket snowmobile parts book which has dimensions of the seals.
