yes, there is. I've posted it up here as well as the "other forum". You can do a search on PO insert and my userid name. No graphics, just text, as I didn't bother to document my tutorial at the time of swapping. It was only an afterthought of posting it, as I figured it might help someone.
If I read it correctly he just wants to change the insert.... But sometimes I no read so good.

this is strictly for an insert swap, not a bezel swap. Youtube has some bezel swap tutorials. It is the same for a UPO as it is for a PO for the insert swap
