Just in the throes of refitting exhaust and I'm finding that there is insufficient thread to secure the collar. The studs were removed because I had some blasting done to clean up engine.
The studs are 47mm long, as part manual says for F model.
The stud is screwed fully home in the head but if I wind it out a bit the collar fits fine. The thread length on the stud is the same both ends, so it's not in wrong way round.
Should I just back out stud from head enough to secure collars then tighten?
