I have an unused GXP BB in my parts box (came with groupset, but I went posh and fitted Hope instead)…how would I know if it’s what you are looking for (I’m not an expert!) it has drivevside stamped on the body and an arrow. It says drive side and non drive side BSA on the threads at either end. There’s 33-13 in what looks like best before font
looks like this

Thanks vickster
BSA is an English thread as opposed to Italian
The easy way to see is .......
You can see the arrow on plastic tube saying the drive side
( theres also an almost unreadable stamp on the thread area say same )
If you look at drive side cups
as if its ON THE BIKE
There will be another arrow on tbe alloy metal part
Does this arrow go CLOCKWUSE or ANTI CLOCKWISE
Thanks
