It's really old, it has shimano selecta cranks/chain rings, as it used to be a ten speed. I know I could move the wheel on the axle, but is it possible to keep my cranks but use a newer chain ring with spacers to achieve a straight chain line?
If I were you, I would probably leave the wheels as they come and change the crank set up. Generally, track wheels come with a 42mm chainline (or there abouts), so I would measure the chainline of the existing cranks according to the Sheldon Brown link above, being sure to try it with the chainring you plan on using positioned on both the inside and the outside of the cranks. From there, if neither position gives a chainline of 42mm (or within about 2mm), you will need to remove the existing bottom bracket and measure its spindle and find a bottom bracket of a length that would position the cranks in such a place that a 42mm chainline is possible. Good luck!
