The mechanical o2 sensor fix is just 2 spark plug anti foulers screwed together with one drilled open a bit to fit the o2 sensor in it. As such it doesnt matter what year/make/engine you use.
As for the downpipe, until there is engine management out, you dont want to do a downpipe or you risk blowing the motor. Im not being overdramatic there.
