OK, here are the numbers for the Hemi emblem. You will have to place the emblem next to the trunk and transfer the stud hole placement. I tried to see if my emblem would come off but I'm pretty sure I put a little dab of RTV behind it so it would not easily be pried off by some kid or souvenir hunter. Since our esteemed colleague put dimensions on his pictures I felt compelled to try the same... ... Anyway, 2 5/16” from the left edge of the trunk and up 3/8” from the crown or body edge to the edges of the Hemi emblem. The Hemi and Road Runner emblems share the same 3/8” placement so they are even with each other. Good luck! Post a picture of the trunk after you get the decals and emblems in place.
