I've got a left and right wiper motor for my 42 but the switch handles don't line up with the covers. Before I take everything apart I thought I would ask for ideas. I have installed them with the flat side down and round side up. If I cock them a little I can make the lever fit but it is a little tight. Also they only have one switch lever on each motor. I guess the speed control was taken off when they were restored. I was told they were poor design and always leak. Should I stick with these and cover the extra holes or look for different motors?
