Bill,
You asked the most pertinent question - why not put it in your profile?
This is off-topic : I've seen people post a question and not receive any answers because they had nothing in their profiles and their question did not say what truck they were asking about. Then, they post impatient "no answers?" or "anyone out there?" when no one replies. The answer is that most people who have answers would rapidly answer (nobody seems to be bashful in this forum), if the question were more clear about make, year, model.
