Are you sure this are 2005 or 2006. They look like repainted 2003. I can not tell from the picture, but are that calipers for the old style (non disc) breaks? If so, I guess these are 2003 boxxers. Do they have some adjustments (rebound, HI or LOW speed compression)?
i got told by the 2005 ones by the person i bought them off and they are vbrake mounts as they arnt threaded, and they have compression adjustment on the top by a dial
Cheers!
