My mother-in-law made this for every potluck from 1975 to 2010

Preheat your oven to 350°F (175°C). Set out a 9×13-inch glass baking dish. There is no need to grease the dish; the chicken will release some fat as it cooks.

Pat the chicken pieces dry with paper towels. This helps the sauce cling better and keeps the finished dish from getting too watery. Arrange the chicken in a single layer in the glass baking dish, skin side up, with the pieces snug but not piled on top of each other.

In a medium bowl, stir together the barbecue sauce and the lemon-lime soda until smooth and well combined. It will look thin at first; that is exactly what you want, as it will thicken and turn glossy in the oven.

Pour the sauce mixture evenly over the chicken pieces, lifting them slightly with a spoon or tongs so some sauce can get underneath. Spoon a little extra sauce over the tops so all the chicken is well coated and nestled in the liquid.

Cover the baking dish tightly with foil and place it on the middle rack of the preheated oven. Bake, covered, for 45 minutes. This allows the chicken to cook through gently and stay juicy while the flavors soak in.

After 45 minutes, carefully remove the foil, watching for hot steam. Baste the chicken by spooning some of the pan sauce over each piece. Return the uncovered dish to the oven.

Continue baking, uncovered, for 30 to 40 minutes, basting once or twice, until the chicken is very tender, the sauce has reduced and thickened into a glossy, slightly sticky glaze, and the edges around the dish look caramelized. The chicken skin should be lightly browned and the meat should easily pull away from the bone.

Check for doneness by making sure the thickest pieces of chicken reach an internal temperature of at least 165°F (74°C) when tested with a meat thermometer, and the juices run clear when pierced with a knife.

Once done, let the chicken rest in the baking dish for about 5 to 10 minutes. The sauce will thicken just a bit more as it stands. To serve, use a large spoon to scoop up the tender chicken pieces along with plenty of the glossy sauce from the bottom of the glass dish.
