[Closed] Raceface BB for repsond cranks - sizing question

Hi, Just a quick question

I have a raceface x type dh race BB on my santa cruz blur with a raceface respond crankset.

I need to replace my BB and I've noticed that there are different sizings on the shell case. Does anyone know what sizing I would need for mine. I don't have the tools to take it apart.

All it has written on the BB other than what I've mentioned above is - 35ft - lbs 47nm.

I've noted that the sizings for the shell casings are

68mm/73mm
83mm

I guess I'm right in thinking that the 68/73mm is the correct sizing for my blur rather than the 83mm which is more for dh bikes?

cheers.
