++ 1 use the Proper Holes , rear of the dropout with some spacer washers* between the Lower fork tip and the Rack strut.
Then bolt to the mid fork braze on Directly.. * presta valve stem ring nuts work great , an LBS will give them away.
For a number of reasons I can't use the lower/rear of the two eyelets
You reasons are probably your self imposed limit, and not meaningful. . Ive mounted those racks Many times in the past 20 years..
So many forks only have the lower Eyelet .. and the top of the rack does Not have to be Dead Level to work fine.
