We will be fitting one of these Xtreme clutch kits (KFD24637-1G) to Danilo's C30 in the next month or so, once they have made their next batch. It seems to be pretty good value @ approx $1700, and can handle at least 400nm. I'll make up some templates for the rear engine mount, and can get a couple fabricated. I have sourced '98 V70XC shafts, as that is what Hussein recommended in his thread. I'm not 100% sure if you will need new shafts as your car is manual already. Have you got a spare RH 850 driveshaft lying around that we could compare? I have my M66 sitting at the shop if you want to come and check anything out/measure
