70 Chevelle Evap Case Help

I have an evap case that I got for my 70 off of eBay, locally, a couple of years ago. The corner of the case is busted off. I know these can be repaired, but I really would like to find an unmolested drivers side of the case if that's possible. It looks like any aftermarket parts are not of the same quality as the OE case.
If someone has a drivers side of a case or a whole case for that matter. Please send me a PM.




Also, Does anyone know what this hole is for? There are no screws holes next to it, and it appears that it may have been milled, as there is a groove around the hole.



Thank you!
Chris
