Edit: Just thought to look. Happy to say my RH fender is far better than expected. Just surface rust. I was a bit concerned about battery acid/rust factor. Battery box is shot, as well as the vapor can.

Two Images:

The first shows the two mystery holes in the RH inner fender. The 3rd hole in the image is for the core support nearest the radiator.

The second shows the two holes into the "pocket" (for lack of better term) of the fender. The LH hole is where the self-tapping screw was used. The RH is where a tapered screw is supposed to go into a fixed nut..........................................Perhaps they were lazy and I should weld it up? Worst case scenario is I have to re drill. That said as the image demonstrates, I wouldn't say it was off by a little. Then again, these fenders are a lot lighter than expected, so may have some room for flex. A few of the holes in the fender had been opened up a bit as well.

You mis-read my post. I stated "As far as I know none of the original screws/bolts were self tapping (notched thread)"

I'm wondering if the inner panels are older aftermarket units. That hole is off quite a bit and that would explain the light weight.....
