I have a 2005 Excursion Limited. We love the truck for our large family. However, I have a problem with the second row seatbelts-the middle seat only has a lap belt and not a shoulder harness. As my children will be getting into booster seats soon, I need to find out if there is anyone who makes or who can make a shoulder harness conversion so I can make the lap belt into a shoulder belt. Otherwise, I will have to get rid of the truck and look for other options, which I would rather not do. Any advice or suggestions would be greatly appreciated. Thanks.
