I have a 2015 convertible camaro. I get an unlatch top message when trying to retract top, but it is unlatched. Took it to the dealership and was told the part needed to fix it has been discontinued. It is the striker plate with sensor, part number Acdelco92241511. Have searched for one or aftermarket replacement with no luck. Does anyone know where i can get this part. or fix the problem another way.
