S3 Tranny Anywhere out there?

[Already a Rover]

Hi - I have pulled my motor for an upgrade and wuz thinking of rebuilding the tranny too.  Now I hear an S3 tranny will bold right in - any sightings by the minions of this rare beast?

If-not, I might farm-out the rebuild - suggestions (Calgary)?

Tomorrow the head comes off and I can have a look at the bores - fingers-crossed.
