We really need to know what cranks you are using. If you are using a
road crank, put the ring on the inside and add spacers as required.
Measure the offset from center line to the chainwheel and to the cog to
determine the spacer size you want.

Scroll down to "chainwheel Spacers" Make sure your bolts are long
enough. The spacers come in different sizes and the bolts can be bought
in different lengths.
Call up loose screws and tell them what you want:
