I believe the salesman for whatever that is worth. Most likely came off truck ticking and the threw new engine in it. Now this is what Ohio law states
Section 4517.61 | Franchisor's damage disclosure statement.
Ohio Revised Code
Title 45 Motor Vehicles-Aeronautics-Watercraft
My two cents after doing this back in the fall. Everything factory, prices aren't terrible especially with places like Levittown online pricing.
Is it really worth saving a few bucks on the "generic" hardware kits? Will they work the same, probably just not something I would risk.
I would never run a different tire on each corner, let alone any used tires like that. I would run a stickier rear then the front though. Used to run on my 03 mach with wide nitto radials in rear with Michelin PSS on the front and it was awesome!!
