Hey Steppinwood, You and I have the same problem. Leaking at the bottom corners and no side locks of any kind. I havnt got to the bottom of it yet, but I didnt think these had side locks with the crank in the center. I havnt come across any for sale on ebay either. Lots of other parts for the windshield, but no side locks. Hmmmmm.
Someone show us a picture, please.
