The ghetto solution would be to use a longer bolt and a stack of washers.
You may also be able to rig up something if your bike has rack eyelets.
Thanks, on my current bike I butchered the struts and put them in the rack eyelets, but the new bike will have a carbon fork and no eyelets. Will try to find a longer bolt and or nuts or washers.
Thanks for the tips.
