American Muscle has the front and rear guards but they are fairly expensive. ZL1addons also has had some less expensive front guards and have recently added the rear guards also. You can search the splash guard threads for numerous pics and comments.
To me, the $6,500 quote is outrageous and totally out of line....mine is nowhere near that amount. Get yourself another quote or two and you should see a substantial difference. Good luck.
Does anyone know if any of the Ford suits ever read or otherwise use this forum? If they do, then surely they know of the desirability of a digital speedo. So, how 'bout it Ford, any comments in this regard?
