Heres a pic of them:
Just make sure the end of the angle iron is below the bottom of the bar or else the bar wont sit up right. I used a hack saw to cut it, and a dremel to widen some of the holes so that the bolts would fit through. Total cost was around $14.
The pic doesnt show it well but I used the bolts that were holding on the plasic "skid plate" to also support the mounts.
