Im not 100% sure,but I believe 1987 was the last year Chrysler used the old style Mopar starter before switching the Nippondenso units. I agree,I love the old sound of these starters and they work just fine. I don't want an old car to sound like a new car. so,now the $64,000 question,how long does yours spin after you let off the key? Since only one person out of those who replied so far thinks 4-5 seconds is excessive it would seem I am not the only one with this issue.
