The rear diff was leaking badly, I think due to a missing balance weight leading to high out of balance. I'm taking the opportunity to switch the 3-bolt for a 4-bolt flange. I've done what should be the hard part - centring pin is out (some heat to soften the loctite made all the difference) and the flange itself is out too. However, the new flange bottoms out on the mudshield before it meets the bearing. I'm aware that a spacer is sometimes required but was under the impression that it was quite a big spacer. In this case, the flanges are very different in overall height but the distance from the mudshield to the inner (bearing) end of the part only differs by a few millimetres - perhaps 32mm on the old flange and 30mm on the new.
The attached picture should make the difference clear - is it a spacer I need, or is something else odd going on?
As ever, thankyou in advance.

and try re-fitting the old race to see if somehow the old and new are significantly different in dimensions (they're identical part numbers), or 2) buy a second-hand diff. I'll try them in that order, probably tomorrow though!
