Frame rail measurement needed

[RJChallenger]

I need the measurement between the rear frame rails at the back , bumperette  bolt hole to bumperette bolt hole. I would like to verify the placement / spacing before , I completely weld everything  back together. Thanks Rob

If you like I can measure my dynacorn rear assembly when I get home.
