I'm in the last stages of refurbishing my MC21. I want to take out the existing standard rear shock unit and replace it with a refurbished SP unit with the remote. Can I ask three questions?

1) I understand that it would be useful to swap the springs over, fitting the longer R one to the SP unit. Is that correct?
2) I have no way to suspend the bike from above to release the rear suspension-would it be OK to use axle stands under the foot peg mounts, or reverse the front pegs and use those?
3) where should I mount the remote unit? Is there an attachment point?

Thanks in advance.

PS my spare fairing panels are in the classified section for anyone to make an offer. Seems a shame to throw them out!
