old TONKA Jeep pickup truck

Well-played-with JEEP pickup truck by TONKA TOYS with still operable tailgate. From the late 1960's or early 70's, I think it used to have a plastic 'grille' on the front that's now long gone. Remains of paper labels on the doors used to say "TONKA". Approx. 9" long x 4" wide, I didn't find any part or model # info on it.
