Didn't see Rud's post before I posted mine, but here it is anyway.
As Ryan mentioned, correct ones are the single indention (no springer indent) fenders for DX, Wasp, Hornet, etc). A set is on Ebay right now, item 251625843058.

An example of the springer indent version is item 161403670693.

Personally, I have one "correct" set now (for my X1) & one with the springer indent as well (for the X2). I actually prefer the springer version, but I wanted to be more accurate on the X1. If you get the version without the springer indent, be prepared to do some slight bending of your front fender.
