I looked but cannot seem to locate a cover that would mount to the front frame on my 4x4 Lariat. the lower front part of my engi ne is fully exposed to the elements
i do see two rectangular holes on the lower front frame and 4 more ..2 on the upper left and 2 upper right that appears to have had something mounted there at one time

 

Are you talking about a skid plate? I figured that your 4x4 Lariat would've come with one from the factory. My 4x4 XLT did. It's fastened with 6 small bolts.

 

The part number for the front skid plate is F65Z-5B018-AC and is available online.

 

Great forum..Thank You!! part has been ordered for local pi ckup. $37 .

 

For the mounting nuts, Lowe or Home Depot or a good

fastener shop should have 3/8 (10 mm) Clip nuts in stock.
