No pun intended, nice one. I'm back in hospital as from yesterday probably for a couple of days.

I've mentioned this a couple of times before on the forum but from my experiance with these kits I wouldn't bother with them (on the 400/4 anyway).
I tired a 1mm lower washer and could still only get 1.5 turns on the top dished nut. Dangerous in my opinion so I went back to the ball race set up.
Unless you are 'going for it' the difference between taper and ball bearings wouldn't even be noticed for everyday riding. If I had fitted tapers I'd be more worried about hitting one of the numerous deep potholes now common on our roads knowing I only have 1.5 turns on the top nut keeping me safe!

My 400 uses a hybrid arrangement iirc it's taper at the bottom and ball at the bottom so I agree. about the top thread danger.
That said the later kits have shallower bearings as I know some members have fitted 400 ones without problems in the last couple of years.
My 500 already had taper rollers, the Pyramid kit was a straight fit as was my 400NA SD.
