1969 Passenger Windshield Needed

My little brother dropped a scaffold on the passenger (left) half of the windshield on my 1969 Mustang. I would like to purchase the half including the aluminum edge and angle piece that attaches to the gunwale. I guess I could replace the entire thing, but I'd prefer to replace the half. I'm looking for a low cost solution. Any ideas would be appreciated.
I also just replaced the old ford 289 with a Chrysler 318. I replaced the engine because new exhaust manifolds were more expensive than a the slightly used 318 my buddy had. The ford engine has an working transmission, new distributor, a starter that was rebuilt last summer, a good alternater, a nice holley four barrel, new rods, and some other goodies.

I would very much like to trade ford engine parts for a windshield that will work in my application.
