Hi all, new member, hope this is in the right place, triumph spitfire mk4, 1974, think it may have a 13/60 engine in it, as engine number begins GExxxxx, anyway my question is, my oil pump drive spindle is seized in as can't turn it with screwdriver, already snapped two distributor drive gear before I realised, I thought it should turn freely, tried with plugs out with a drill and fitment no luck, does this I have to remove pump,wj
