a base having a plurality of studs configured to fit into openings in the grating, said base including a forward support member;

a load transferor pivotally connected to a rear end of the base;

a plurality of front clamping teeth attached to a front end of the base;

a locking assembly configured to co-act with the front clamping teeth to secure the base to the grating;

a lateral restrainer configured to restrain lateral displacement and lateral shifting of the vehicle relative to the grating; and

a face-plate attached to the load transferor by a hinge pin, said face-plate including:

a body having a front side, a back side, an upper portion, and a lower portion,

a plurality of spaced-apart arms connected to and extending from the body, and

a plurality of spaced apart engagement pins mounted in and extending from the back side at a bottom of the body and configured to be inserted into cavities in a front face of the forward support member, each said engagement pin including a mounting head and an engagement leg connected to and extending from the mounting head, said engagement leg includes an attachment end attached to the mounting head and an opposite free end, said engagement leg including a bottom engagement wall, an inner engagement wall, and an outer engagement wall which define an engagement slot between the attachment end and the opposite free end.

2. The vehicle wheel chock of claim 1 , wherein for each engagement pin, the mounting head defines at least one pin receipt hole, each pin receipt hole configured to receive an attachment pin.

3. The vehicle wheel chock of claim 1 , wherein each engagement pin is made from stainless steel.

4. The vehicle wheel chock of claim 1 , wherein each engagement pin is molded into the body of the face-plate.

5. The vehicle wheel chock of claim 1 , which defines a plurality of openings configured to receive an upper portion of a U-shaped hinge pin, and a plurality of hinge pin slots configured to receive a lower portion of the U-shaped hinge pin.

6. The vehicle wheel chock of claim 5 , wherein the plurality of openings extend through the arms of the face-plate, and wherein the plurality of hinge pin slots are on opposite ends of the body of the face-plate.

7. A vehicle wheel chock face-plate for a vehicle wheel chock for a vehicle on a grating, said vehicle wheel chock including (a) a base having a plurality of studs configured to fit into openings in the grating, (b) a load transferor pivotally connected to a rear end of the base, (c) a plurality of front clamping teeth attached to a front end of the base, (d) a locking assembly configured to co-act with the front clamping teeth to secure the base to the grating, and (e) a lateral restrainer configured to restrain lateral displacement and lateral shifting of the vehicle relative to the grating, said vehicle wheel chock face-plate comprising:

a body having a front side, a back side, an upper portion, and a lower portion;

a plurality of spaced-apart arms connected to and extending from the body; and

a plurality of spaced apart engagement pins mounted in and extending from the back side at a bottom of the body and configured to be inserted into cavities in a front face of a forward support member, each said engagement pin including a mounting head and an engagement leg connected to and extending from the mounting head, said engagement leg includes an attachment end attached to the mounting head and an opposite free end, said engagement leg including a bottom engagement wall, an inner engagement wall, and an outer engagement wall which define an engagement slot between the attachment end and the opposite free end.

8. The vehicle wheel chock face-plate of claim 7 , wherein for each engagement pin, the mounting head defines at least one pin receipt hole, each pin receipt hole configured to receive an attachment pin.

9. The vehicle wheel chock face-plate of claim 7 , wherein each engagement pin is made from stainless steel.

10. The vehicle wheel chock face-plate of claim 7 , wherein each engagement pin is molded into the body of the face-plate.

11. The vehicle wheel chock face-plate of claim 7 , which defines a plurality of openings configured to receive an upper portion of a U-shaped hinge pin, and a plurality of hinge pin slots configured to receive a lower portion of the U-shaped hinge pin.

12. The vehicle wheel chock face-plate of claim 11 , wherein the plurality of openings extend through the arms, and wherein the plurality of hinge pin slots are on opposite ends of the body of the face-plate.

13. A vehicle wheel chock for a vehicle on a grating, said vehicle wheel chock comprising:
