Ok guys, I'm getting closer and closer to getting the 420 in there, but I have one question. Charlie (pinhead) outlines a procedure to make an adapter for the pilot bearing on an SM420. He offhand mentions that this is only necessary if you do not buy an adapter. On Mike Smythes' site he mentions a bearing needed "for Warden's pilot adapter." Is this Warden's pilot adapter what PH is referring to? and if so where do I get one? (I don't trust my fab skills, I need to save time, (school starts waaaay too soon) and I recently had a pilot bearing failure while on the trail and its NOT fun). Or maybe I'm way off here and someone needs to smack me? ??? (I did have another soccer practice today ) Any ideas from those of you that have done the swap? Maybe some invaluable wisdom from Mike or Charlie themselves?
