Vinyl top HELP

Hey guys, I'm a new bee and I really like the site!!
I am trying to put a full vinyl Top back on my 1970 duster. It had bean removed and all the tabs and screw holes are gone!
I finally got the trim pieces I needed but I cant figure out the exact locations of the tabs.
If someone has dun this before or have a duster that has the top trim removed and didn't remove the clips yet, if you could give some pics that would help a lot!! Thanks
