Restoring 1969 dodge dart GTS after 24 years

Well I have attached a picture of the fenders with some notes to show what holes are on them and what I think they are. Being the fenders were sand blasted 24 yr's ago (i had somebody do it) and the rest of the car still has the original paint I will take some pics of the rockers and lower qtr. pnl. tonight and repost. I will also take pics of the holes themselves if I remember they go in at an angle??

In regards to the build sheet I found it in pc's falling out of the headliner when we started taking the interior out to start this project. I have most all of it just in pc's (talk about a puzzle) Can this be a early 1970 build? that is why the build sheet is multi colored?
Thanks for the feedback
