1x 2.5mm spacer on the drive side for 73mm

For a 73mm you only need 1 spacer (of the 3 you got with the bb). And it goes on the drive side.

Beat me to it!
Unless of course you're using a BB mounted chain device or front mech, where you'd use no spacers..... or did that just complicate things

to one and all I thank you

yes lets complicate things
as far as i know HTII BB's are 50mm chainline so it is possible that if using a device or your frame is not the exact 68or73mm then you might need other smaller spacers to get the exact 50mm chainline...
