I think you may still have it, or at least my email
Re the panels, I might sound like alot of work, but in reality it isn't.
Firstly the rear quarter is spot welded to the C plilar behind the trim, along the boot shut to the inner wing (possibly don't know without looking), to the rear panel and the boot floor (seam is obvious with the bumper of), glued to the rear inner arch (before it rusted out) and a handful up the rear door shut.
Much easier to plug weld and seam seal than to bodywork patch panels
The only additional work is removing/replacing the rear screen to access the bottom corner where the quarter meets the parcel shelf.
And you don't have the complication of accident damage before the new panels fit.
And did I mention that it will significantly improve access to the inner arches for you
It might seem like more work because it's a bigger area, but it should me more efficient, and therefore easier, especially given your circumstances
