I have a tacsew T175-2 blind hemmer. I need a new machine setting vice to clamp the machine to my table. I also need a knee lifter rod shaft, a lifting arm clamping screw and a lifter rod sleeve. Can you advise me about the availability of these items. My Hemmer is about 20 years old and since I do clothing alterations, it is most vital to my business. Any help you can give me will be greatly apreciated`
