[]Bought a fuel cell and mounted it in the trunk many years ago.
Like the man said......but.....mine's functional with a Charger flip open cap on the outside.
Oh, yeah. The 25 gallon cell helps with the range of a BB under the hood.
Hell, If your media blasting, the windshield and backglass should be the least of your worries..... getting the headliner in and then the glass... that will show your mettle of a REAL mopar meckanik. ;)
Just a thought.........If the kickdown linkage isn't set up correctly, they will shift like it can't make up it's mind and seem like it's slipping. Just my .02 worth. Don't sell it, fix it!
