good luck with that swap, i switched from an auto to a 5 speed a while back only to have to pull the tranny back out to fix that seal. i put a fidanza flywheel and stage 3 spec clutch in form howell which took damn near 2 months to get, anyhow i would be driveing along and slowly roll in to it only to have it start to slip i thought that this was due to the breakin of the clutch but while i was doing the clutch restrictor mod i decided to look in the bellhousing only to see the light coloring of grey your talkin about so i pulled the tranny and sure enough thats what was leaking you can really tell when you take the throughout bearing out and look at the bottom where its positioned downward.
