I have the sizes for the front & rear Getrag 240 seals.
These are the factory GM/OPEL parts. Here is a pic.
OGTS sells these, BUT at over $20 & $30 per seal.
You should be able to match them up at a parts store.

Smaller: KACO 36 DGS 30 - 42 - 7 RF01
With an ARROW pointed CLOCKWISE

Larger: KACO 35 DGS 38.1 - 52 - 10 LF01
With ARROW pointed COUNTER CLOCKWISE
and 90 112 741 11 - 134 GM

The numbers after "DGS" are the Inside & Outside
Diameter and the Thickness of the seal in Milimeters
The "R" and "L" are for which way the part rotates
in the seal. If you go to a part store to match these
#s, MAKE SURE you get them rotating the right way
or they won't seal properly. Looking inside the seal
you will see slashes built in going to the right or left.
