correct emblems and placement on 70 swinger

Here's some photos from my 318 Swinger. Things to consider is how the holes were filled. If they were welded, it can be difficult to cleanly drill back out depending upon the weld. You might have to shift them a fraction.

They may have just been filled with filler. Look behind the panels and look for either weld marks or body filler coming through like dried Play Dough. Either way there's likely a skim coat of filler over the entire area.

Regardless of the measurements and method you use, I would tape up the entire area to protect the paint. Make your marks on the tape and then check the marks against the actual pegs on the emblem. Adjust your marks as needed making certain the emblem is straight and level. Remove the tape after drilling the holes. Measure ten times drill once, right?

The retainers are like this but shop around for the best deal.

The emblems on both sides of my car are not placed exactly the same. The measurements on each side are also different due to the curved top edge of the quarter panel.

The top photo is the hood Dodge, the next is the Dodge on the trunk followed by the left side and the right side.

Hope this helps along with everything else posted.
