I'd use a factory cam sensor, but unfortunately Ford never made one for a 9.5" deck motor.
My distributor is out and it turns out the dist shaft is slightly bent, which explains why the bronze gear is wearing even quicker than they normally do (it's a billet steel solid roller cam combo).
I could get someone to make a hybrid body/shaft/sensor as a custom piece, but a place in the states makes a nice billet piece that will bolt straight in.
