add spacers between the eyelet and the mounting point on the rack , a stack of flat washers will do , or go to a hardware store ,
you will find nylon ones .

or hack saw off a piece of tubing to be there right length/thickness. the original 70s blackburn rack that one copied
included the spacers in the parts bag.

of course the rack will negate some of the way a carbon fork feels as it will dampen its motion ..
