Does anybody know the sizes / part numbers for the three external seals on a Getrag?

These would be the front shaft seal, rear driveshaft seal, and the little seal on the shifter shaft. I was thinking of replacing these if I could before installing my Getrag. It would be nice to see I can get replacements before attempting to remove my existing seals.

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.

Dean I am no seal expert, but I would not hesitate to install a 38mm ID seal onto one that asked for 38.1mm. Where did the dim 38.1 mm come from anyway?

Q & A

Q: What is the difference between a GM/Opel seal and an other brand?
A: A GM/Opel logo, and that's why you pay gold for that thing!!!!!

It doesn't matter what brand you use as long as it has the same measurements.
Just measure the axle Ø and the Ø and the depth where the seal fits into.

I have been calling my local auto parts trying to match the part numbers with no luck. Did anyone ever get these from the Auto Zone, O'Reilly, etc, stores?
Mine is weeping a bit. Since the tail shaft is the same id as the automatic GT and/or manta, is the seal not the same? Anyone know the dimensions of the tail shaft seal for the automatics?

I assume they did, since there are no additional threads and I've seen your car!
