I know Tubus has them on some of their racks. I only have one set of eyelets and would like to add a rack to my Raleigh. I know I could get longer bolts and mount everthing to the one set or I could go with P-clips, but I'd really rather find a rack with eyelets. Any ideas?

Using the one set of eyelets is not a problem. Mount the rack next to the frame and the fenders outermost. I have used this method for years with some very heavy loads. P-clips are a messy solution to a problem you dont have.

+1. I've shared eyelets on many bikes without issue.

p-clips aren't bad either if you have to use them. I've never had a problem with them anyway.
