Paul,
Researching parts is complicated by simplistic "application" specs and not dimensions.
My windshield is flat and 12" high. I have the 1/2 inch knurled drive shafts and they are a bit worn, a set screw would help.
I do not recognize the SPW blade to arm attachment on your 33. I have 10" Mini Cooper blades with a standard M/F slide latch coupling.
What is the length of your Coupe ANCO 44-01 arms? I find only application data on them, not dimensions.
