Once getting the old switch out of the dash, the switch handle is different then the International switch. What I did was to break off the AMC switch handle and handle mounting at the two spot weld/rivets, and super glue the AMC switch handle onto the new International switch, after removing the International handle of course. When installing the AMC handle on the IH switch, be sure to put the bottom side of the the AMC switch in position that was the top of the International switch, this is so the switch will work with the indicated switch positions on the dash. It would work if the switch handle is installed in the same position as the International switch, but function would be opposite. Modify the switch like this and it will work great, now I have heat! Yippy!!!!!
