I don't want to chop and modify it. Thanks.
Or I could simple use new modern BB right away? I doubt about compatible.
Currently use Miche Premato 144bcd JIS sqauretaper BSA threaded (I think).
I went down this rabbit hole last fall looking for sub 165mm cranks.
There are several BMX or fixie cranks that are JIS square taper but they are for 110 BCD chain rings.

You can get a 110 bcd to 144 bcd adapter, but not sure what that will do to the chainline.

The only track specific crank set I found was the Rotor ALDHU. It has a 30 mm spindle, but the BB is for BSA 68 shells.

If you want a power meter, then you can get the Rotor with a Power2Max spider.
