Doin a valver in a nova blah blah...
engine is from a 94 Cav SRi so it has the multiple 'poly' crank pulley held in by a single (e20?) Female torx nut.
I was hopin to get the single V used on early Astras but, lookin at the EPC, it as 6 bolts holding it in, so i assume it wont fit my shaft?
which one do i need? the twin V one, and either leave the extra V and hope it clears the inner arch or get it grinded/machined off?
