that mount is perfect!!!....I would buy one for my silver Hemi Duster. IF you make more than one (to defray your expenses), please let me know.
Looks like no grinding / drilling required and for some of us with "finished" firewalls....you have the answer.
I have found the "universal" mount required modifying the factory hole....and the inner fender dented for clearance. The Titon slave solves that issue.
