TRD Supercharger Nose Drive Seal

I have the TRD Supercharger on my '12 and the nose drive seal is leaking. With only 6 oz of fluid I can't say if it is "bad" but it is a a spreading pattern but not dripping yet. Something of a class 1 leak.
I am trying to get a part number for the nose drive seal. Dealer said all they can do is replace the entire nose @ $2000. Contacted Magnuson and was only told to contact SCOL for a rebuild. Contacted SCOL and they gave part # EAT-101687. I'm concerned that it doesn't list the MP90 as a compatible interchange.
Can anyone help verify that this part # does interchange or give one that does?

Thank you in advance.

For a follow up, I finally got to doing the repair and indeed that was the correct seal/part number. Could only retrieve 2 oz of fluid but only got about 3 oz back in before it was over flowing out of the fill port.

It is a month later and I found the new seal is leaking badly. Took it apart and the inner rubber ring has disappeared from the seal. Replaced it with one from ZZPerformance. Fits well, though it is rubber coated instead of exposed metal. Now to wait and see how it fares.

Just an update. It has been a little short of 15K miles and the seal has held up. After going through that second install I've wondered if I set the pulley too far on to the spindle and that caused the premature failure.

I did the work myself. 2 snout seals, a pulley puller, and gear oil, maybe $100. The URD SureGrip pulley and press fit tool added another $150.

It was a few hours because I'm slow. Wasn't complicated or involved, but the press fit pulley is a PITA coming and going. The seal itself was pretty easy, using the same trick on rear main seals on old bronco IIs and such, inserted a couple of self tapping screws and pried on them to pull it out.
