Hi Wozza, just had athought re your previous post when you said" 'cos of new plates ,not enough length left to get the 2 nuts on " or something similar , now very familar with the 6 springers ( putting it mildly ) but wasn't it mentioned that some of these units had less plates than others and so couldn't you reduce the number to suit, just my 2 pennyworth but def not said from a point of knowledge. best of luck getting it sorted ,BobH.
