That 110mm spindle is too long for 75's not to mention the wrong taper...you need a Sugino superlap BB. I think they're 107mm and ISO NOT JIS taper.

109 symmetrical iso for 75s..
see here for track cranks: https://www.businesscycles.com/tr-refspec.htm
road cranks probably a 107 or 103 depending on chainstay clearance

It looks like this should give you the information you need.
For a 42mm chainline, you could use a 111mm spindle with the ring on the inside of the spider. (someone check me on that?)
For future reference, chainline measurements have everything to do with the type of cranks, bottom bracket and hubs. The frame is not a factor.

extra bitter
I don't think 111mm is available in anything reasonable (Campy makes one, but fughedaboutit). A 109 or 113 should be close enough, assuming it's symmetrical.
