I need the stationary belt piece for the drivers side rear of a K5 (1986 but I don't think the year really matters), I don't care what color. We were surprised with twins at our first ultrasound so I find myself in need of a way to secure 2 car seats and a booster. The other 2 belts function fine but the 3rd is missing that half. I am building anchors for the car seats but just need the 3rd belt to be working. I'd go with new style seats with 3 shoulder belts but it's way outside the budget.
