A mate of mine with a Celsior has lost the hydraulic fan nut , [ it probably has never been on there as it's a lefty thread and can't come off !! ] anyhow there are two types of mounting for the pully boss , one is on a parrellel shaft with a keyway and the other is actually on a taper with no keyway .
I already found a keyway nut but it's too big !!
The two different types have two different nuts !!!!
I either need a taper nut or need for some-one to tell me what thread size and pitch it is so I can make one .
His car has already been down for a month so he's getting a bit frantic !!
