In case you still need depth of spare tire well it’s 6" when measured using a straight edge across the trunk floor above the fuel tank, in the rear it's more like 6 1/8". Also the fuel tank strap brackets are located straight back from the openings in the cross member for the tank straps and pretty much centered on the ends of the spare tire hold down bracket (if that makes any sense?).

...Mopars are always way out back
Between the muddy river and the rusty railroad track
Yeah, the Mopars are always hard to find
But you can always find a few
There’s Cordobas and Furys and Darts and Dusters too
There’s a Diplomat with a Swinger
A new Yorker a Demon and a Scamp
And there’s a 68 Barracuda grill with both headlamps...Slaid Cleaves - Skunk Juice
