Well my hood flew up last weekend and during its destruction of my cowl area it crushed the linkage to the wiper arms. Anyways im getting the Wiper Delete things from Late Model Resto, and i figured id lose the wiper motor since i wont be needing that anymore. I disconnected the 3 bolts that hold it in place, and its still connected to the linkage. I see something that looks like a retaining clip holding it in place, is that all that need to come off to remove it from the firewall? Also there is goin to be a good size hole in the firewall, any ideas on how to plug this hole up??
