When you log in there is a "Remember Me" box next to the sign in box. Click on the box each time you log on and the problems go away.
A five year old can figure out how to post pictures on the site so I went and got a five year old to show me how to get into the "Go Advanced" box at the bottom, click on the 'paper clip' on the top, then 'Browse" through my pictures or computer to add to the thread. Kids are amazing these days.
I found CFR's on the doors, under paint on the glove box door and written in pen on the dash. Never have checked the top of the drivers side frame rail so that should be on the list. After a good scrubbing in the cab or a light sanding on the doors, things start to appear. The original OD paint was tough material and some of the lettering I've hit with cleaning products like "Goof off" wouldn't even smear so some of that was enamel like paint too.
Good luck with the photos, in 5 years of MV addiction I have only seen 3 - M207's.
