dohc motor didn't come out till 1979. 1978 was still a sohc motor and the last year. Exhaust should fit most dohc motors at the motor but cant say if the mount to the frame is the same or not, my best guess would be it should be able to be made to fit.

Ok thanks-as long if its a DOHC i will be fine?.I don't care about the mount-it just needs to be right on the headers and flange holes.
