Sorry for the delayed response - don't get much time to actually log in and check my account at the mo.
If your SC10 is a new one, you will hopefully find 4 shims in the box - AE started putting an extra 2 in the box after the first batch. If not, get in touch with CML and plea with them - they might stuff a couple in an envelope for you...

Good luck with it
Andy

Fantastic! thanks Andy, thats perfect.
Ill get on the case and order up some more shims! lol.

Hello Andy, just a quick question for you regardging the shimmage on these here SC10's. Please forgive me for sounding a bit dense! but the 2 shims each side that you recomend, am i putting them internally under the end pin on the inside of the outdrive, externally between the out drive and the diff casing or just over the outdrives as normal between the diff and the bearings, silly question i know but i am blonde and easily confused by the number of shims! lol, ive never built a gear diff before.
