70 road runner rear bumper guards location

Hello… Seasons greetings! Is there any of you guys that know the exact location for the 1970 Plymouth Road Runner rear bumper guards?

Rick Ehrenberg (member here) probably has a factory diagram for that.
Photos of untouched original cars with them should help, see if locations align with other bolts, etc.
I got nothin' better for ya, as my only '70s were a Satellite wagon and a Barracuda, and my Duster's no help...

I am no x-pert but the ones i have seen over the years look like they are right below the trunk gaps!

I don't have the dimensions handy...but here is a photo of my 70 with factory rear guards. If no one comes up with the dims I will see if I can get them this weekend. Joe

5 3/8" from center of outside, top bumper bolt to center of bumper guard hole.

And as a double-check, looks like they line up with the trunk lid/quarter gaps.

Thanks for all your help! Merry Christmas!
