Thanks for the ideas, I called the dealer and the price he gave me was $741. so I thought I try something else for now.
Just one other thing I would like to share with you, I owned this car for 17 years, I have 301K miles on it.The only thing I had to change on it is the voltage regulator some years ago (that is other than brakes, muffler and the normal maintenance things), does any one have similar experience ? should I expect the car to fall apart soon though it does not appear to have any problems other than the HB at this time.
