Kev, do you run the Ultima diff plates in the Lazer transmission? I thought you needed the dedicated Lazer ones as the smaller diameter plate is needed to fit inside the crown wheel. Never tried the Ultima ones so interested to know if they do work.
Lazer ones used to be WBD04 but it's now a 9**** number and I can't remember it (so long between diff rebuilds that I have forgotten
)
