Bluerun,
I’m in the process of doing the same for the exact same reason on a 2007 Pilot 34. Only difference is I’m the one who installed the new wiper motor which caused the problem. It seems the screw securing the pantograph wiper arm pivot sticks out on the inside and the motor was actually mounted with a rubber shim on the motor shaft and not flush to the glass.
Ocean Dynamics in Miami, where I am, is making the new windshield. They came out and templated the frame and the port side. They are scheduled to install next week. Call them at 3057701800, Ron Kappy is the guy I’ve been dealing with. If you have the same model Pilot, they may be able to just duplicate mine.
Just to plug the hole, I bought a sheet on thin Lexan from Home Depot and installed with 3M VHB double sided tape. Very flimsy but keeps out much of the rain.
Good luck
