Bottom line --- 5 hours of labor at roughly $100 per hour = $500. That seems a bit excessive (to me) for this job.
But, that is what the local Ford dealers want. If that is what it takes to get the job done RIGHT, then I guess I'll "bite the bullet" and pay the price.
Still hoping someone will come up with a better suggestion on where to go in the Kansas City area --- I can wait a few (several) days to get this done!!!
