My 2001 crew cab only has the rear center lap belt which was fine for a 5-point harness child seat. The seat is coming out now and I don't like the idea of the use of a lap belt only (we have 3 children). Is there a way of converting/installing a standard seat belt like the have in the 2003 and up models? Truck has tan leather interior.

suburban 60/40 seat has a center lap/shoulder belt.??
