Did this get resolved? I am just having mine rebuilt with new bodies and nuts. All the body lengths are available and nuts to suit. In stock now.
Bodies are aerospace grade alloy that has been hard anodised, the colour is beautiful, like gun metal grey. Nuts are equally as stunning.
(Ti lock nuts for the end of the rod also available)
So if you or anyone else is in a bind and need bodies (3 lengths available) and / or nuts, help is available. (and of course seal kits, bladders etc which is all widely available anyway)
(Would post a pic, if only I knew how. One day I will get that sorted.....)
