Bill of Sale

1956 Turn signal switch

The trigger spring is GM part no 1930005. It was used on 1955-60 Buicks. Original parts and reproductions are available on the Net as you have seen. Old Buick Parts shows it as their no CS550.

The detent spring is part no 1930043 and was used on 1955-56 Buicks. Haven't been able to locate one yet after a brief search. Maybe someone will be parting out one of these cars that can provide a spring.
