fitting an off the shelf SKF bearing for IMS

[jimk04]

Im taking the trans off the car next week primarily for a clutch job.

I have decided on using a simple SKF/NSK bearing as one has been in there for 100k miles so far no problem, and the main reason is that the engine will be removed also in about a year to swap in another engine I am building.....so I dont want to spend a fortune on a mega bearing upgrade for this engine for a short time.

My questions are....

. should I get standard clearance bearing or a C3?

Assuming I cant get any oil into the IMS, should I leave both rubber seals in situ on the bearing....maybe remove one seal and repack with grease before refitting both seals??

Thanks
