I'll have to get the "very near gauge" out Ash and measure my front one, it looks to be around the 23-26mm area.
As for the rear one - don't recall ever seeing one on it.
When i first got mine, the Nivos were leaky so needed changing, it also rode like a rowing boat, mid-Atlantic during a Force 10 storm!
Got a set of NOS KYB shocks (same as yours, was surprised when they landed as was expecting any old brand!), NOS front and rear springs (Suplex rings a bell - Suplex is a subsidiary of one of the big spring makers but can't remember which) for just under £125 so no real excuse to not do all 4 springs and shocks.
That improved the ride/handling considerably along with new spaceship bushes, drop links on the front ARB, sorting the tracking and a set of new, matching tyres.
Now i just want to control the body roll
