You also need to check the fork height, they are usually pretty well within the range on anything 700c/touring, still. Since your frame does not have a fork currently yu may need to mock up the height.

You can search a wide range of parameters within a catagory.
You don't need 2 eyelets, it's a throwback to when a lot of fenders had a top wire, rarely seen these days. Though most frames with a mid height BO will have them anyway.
