Press fit square taper bottom bracket

The bottom bracket on this frame is a bit unique. I have only seen press fit bearings for cranks with an attached spindle. But this one has a square taper spindle in it. 

It's a 117mm spindle, and I'm looking at replacing it with a shorter one to bring the chainline in to fix issues with the Deore DX to Dura Ace conversion. I think I will have to hammer it out from one side or the other.

Klein bikes use 35mm press fit bearings. Mine has a 117mm square taper in it.

My chainline with a triple crank is around 47mm, I may need to bring it in to 45 or 43 for optimal dura ace specs.
