My adjustable wastegate actuator broke and I need a new one. I was wondering if I could use this one 1984 1985 1986 1987 Buick Regal Grand National Turbo T T-Type GNX ADJUSTABLE WASTEGATE ACTUATOR #6696 on my 1985 GN. I know it has only one vacuum line instead of two and I am not sure if it mounts the same. Thanks for the help.
