DL,
If its an Extreme VFT or a Pro40 Wheely then I see no reason that it shouldn't as the risers are unchanged.......I'm guessing all other models might be a problem due to the addition of the flared arrow shelf. I guess it depends upon how far up the Loesch grip extends up the side of the 2003 model.
I will take a picture of both risers side by side so you can do at least an eyeball comparison.......I'll get that on here tonight for you.
