The grill in the yellow Cherokee is NOT a "razor" grill, it is refered to as a "Rhino" grill but you are correct in that it is found in 63-69 FSJ's.
The "Razor" grill is found on 66-69 Wagoneers, 74-78 Cherokee's and 70-78 J-trucks. The grill for an 82 Cherokee is refered to as a Muscle grill and is found on 80-85 Cherokee's, and on 80-88 J-trucks.
And yes they all interchange with some simple mod's.
