@ gstoli - What shops in Boston have given you a hard time? Give Motor Sport Garage a call in Cambridge/Allston. I found them in the Nor'Easter, the local PCA mag.
I have taken in parts there before, just made sure I told them over the phone what I had. This way they could be sure to have any extraneous parts on hand that may be needed to complete a job. Not sure what they would charge for the work you are looking to have done.
