Preheat an electric or gas grill to 250 degrees F.
Rub all sides of the pork with the seasoned salt and lemon pepper seasoning. Put the rib sections on the grill. Prepare Fred's Special Spray by mixing the lemon juice, vinegar and Worcestershire sauce. Put this mixture in a food-safe spray bottle. Spray the ribs with Fred's Special Spray. Cook the ribs until they are browned, about 1 1/2 hours, spraying often with the sauce. Put the ribs in a 4-inch-deep stainless steel pan with a lid. Spray the ribs once more and close the lid completely. Increase the grill temperature to 300 degrees F. and cook the covered ribs for 3 hours more.
For the second cook, you can substitute a baking bag for the covered pan and cook the ribs in a 300 degree F. oven for 3 hours. Have your butcher cut each pork rib slab in half lengthwise and then into two-rib sections. They cook faster and are easier to handle and eat.
