correct emblems and placement on 70 swinger

I have a 70 swinger im prepping to be painted in the near future. My problem is it was painted back in the early 90s and all emblems were removed. Now i have no clue where the exact placement of dart swinger emblems should be on the quarter panels. Does anyone have a measurement to get close??

Also on the trunk should there be a dodge emblem there or a dart swinger emblem??

I do have the origional emblems and some repops that i was given. But not sure how they attach? They have the sharp pins on the back im guessing there is a washer type item that must hold them on from the rear??

Any help will be appreciated thanks
