Finally made the 11s!

Sorry its been so long just saw this...

And you probably talked to my dad, he has a 67 coronet and I am pretty sure he is on Moparts. But I am pretty sure the rear wheels are a 5.5 back space on a 10 inch wide rim with a 275/60 MT radial. The springs are moved in just a little with the s shackles and the boxes.
