If you would happen to find more than one 2M-HD please let me know. Were they popular in Iowa? I'm from SE South Dakota and have never seen one in person, only pictures. I might have mounting brackets for your 460 but I'll have to look around.
Was called today from a pair of brothers that are only 30 miles from me that are going to bring down a 2 MHD on a IH M it will be the second one I have seen the other was from Penn. that was at Half Century of Progress last yr.
