I'm trying to do a Freehub body swap on an old 600 tri-color wheel. The original body was 7S Uniglide/Hyperglide. When I put the 8/9/10S body on (labeled Deore XT according to the LBS) and tighten the 10mm fixing bolt it gets way too tight and won't freewheel. It binds really bad. Am I missing a washer or something? The body freewheels fine when it's not attached to the hub.
