I did that a few years ago, just as you describe, after a failed recovery shattered my back window. I documented the process with captioned photos on another LRO's website but I regret to report that the website went away and I lost all that documentation/commentary. I do still have the photos.
Thanks so much :thumb: . I havn't had a look at it yet, but you have put my mind at ease. this is but one of many rust problems I have. Another is the almost completly missing air plennum below the windshield. Serves me right for not seeing the car before I bought it
