Seals Speedmaster ??

Currently restoring a Super Speedmaster, looking for the last parts... prop shaft seals.

I need 2 of these ?? or some compatible.
#26-60109 superceded to #26-60109A1 NLA ( Twister IIX 1974 manual )
#26-60110 superceded to #26-60109A1 NLA ( Twister IIX 1974 manual )
#26-38676 superceded to #26-55979 NLA ( ssm 1965 manual )
#26-38677 superceded to #26-55979 NLA ( ssm 1965 manual )
I "think" they were the same, or were there a difference between those speedmasters ?? ( shaft I.D or case O.D)

Seal I.D= 1.000" O.D=1.380" h=0.255"

It's hard to find inch seals in a metric country :( , anyone got any hints about were to start looking .
