It had a bit of play in it which I wasn't very happy with, but it was a good 4 or 5 years ago now so others may have improved.
Ben: Thanks for the JJR tip, hell of a lot cheaper than the Works Bell units. I've not really considered using them due to my past experience, but may do now if you're happy with yours. Was it as tight as the Sparco unit, or relatively close to?
Stephen: That's what I'm wary of mate, but perhaps they've improved over time? This is my current unit. It has no locator but it pretty easy to line up. But since the grease has gone from it it has a little play.
