Started cleaning up parts and while messing with the K member I recalled that on a separate thread we weren't able to get a date off of the K member when I was trying to figure out about when my car was built. I checked the area in the front of the K member where the date code should be stamped and found this...
The consensus was that that number wasn't a date code and that there was probably another number near it. I haven't checked the underside thoroughly yet, but there isn't another number on that forward facing portion. I did find these...
I pulled the back window and found rust, as expected. I need to clean up a bunch more to see how bad it is but I am happy it is out. It had plenty of adhesive and what looked like grey plumber's putty jammed in under the trim.
I know the 4 door parts car has a different shaped back window but I am thinking it might still be able to provide some patch pieces for the rotted areas, rather than having to form the angle.
