Place the chicken, skin side up, in a single layer in a medium-size baking pan. In a small saucepan, melt the butter over medium heat. Add the brown sugar, vinegar, and seasonings; stir and pour over the chicken. Bake, uncovered, at 400 degrees F., basting twice, for 40 minutes.
In a large bowl, mix the stuffing ingredients together. Remove the chicken from the oven, drain the drippings from the baking pan, reserving ⅓ cup. Pour the reserved pan drippings over the bread cube mixture; toss lightly to mix. Place the stuffing around the chicken in the baking pan. Return to the oven and bake for 25 minutes longer, or until a fork can be inserted into a chicken piece with ease. Serve hot.
