Question for you guys, how much play (if any) is acceptable in the top shaft - as far as in/out movement goes? My stock top shaft has a lot of play and I just replaced it with the MIP shaft. It's better than it was, but still has around .40 - .50mm of play in it. I don't remember my RM car having this issue. If shimming is required can someone recommend a set of shims? Thanks.
