Engine: Ok, I understand that John was basically limited to the PRV for the D...so why was our PRV designed with such a low output, when so much more was/is possible? Keys: Since I have an early '81 with two keys, I'm curious. When they went to the one key system, did they keep the old ignition key and change the door lock cylinders, or keep the door key and change the ignition cylinder? Inquiring minds want to know!
