Another update...
I tried putting the new seals in today and reassembling the unit... no go. As I mentioned earlier, the rear high speed seal is a custom jobber with a non-standard thickness dimension. I scoured the catalogs of various sealmakers and purchased the closest seal I could but I can't get an out-of-the-book seal short enough to allow me to get the snap ring in behind it. The ATI seal is just an oddball. I could machine the supercharger housing to fit the new seal but that would be, well, dumb. LOL.
It looks like I'll be sending the unit in to be rebuilt since the only other option is to have a seal custom made. The good news is I figure I'll have them "upsize" it to a D1SC while they're at it.
