Looking for a reasonably priced pto cover for my 1964 110....
The motor in mine was changed some time ago. It is a 1966. So the cover has the ribs in it.View attachment 6785 View attachment 6787
He is correct they were flat with no ribs in those years. They will all work but some are very picky about having the correct items with their units.
The first pic side cover is the one u need on another 64 , the other is on a 67 you can see the difference is basically just the three ribs on them
