hey guys, built my b4.1 yesterday and went together really well.

I have built a bunch of B4's so I did not use the manual but my mate who built his today noticed that there was a new 16x10mm outdrive bearing which is different to the B4 which was imperial

this must mean that the diff outdrives are also a running change. did anyone else notice this change? it means I have a bunch of parts that are no good for B4.1 now.
