I will be able to help you.
We only use new mainshafts in our Stage 1 and 2 boxes, so I can either sell you a new one, or I might have a used one that will be usable, provided you carry out a big bearing conversion, which does involve some machining to the casing.
You up for it?
Even if you fit a new mainshaft, I'd recommend the big bearing conversion.
