Does anybody know why the Rallye propshaft rear coupling / donut has a balance weight attached? I believe the early syncro did not have this. What I really need to know is what would happen if I removed this. I know the Rallye front donut will fit fine (I have tried it) but I am worried what effect it will have. I would get the propshaft balanced if it would help make the propshaft OK. The reason I would like to do this is it would give me more clearance for my exhaust. Any advice much appreciated. Richard
