So we need to replace the motor to my mom's Singer 29K60 machine. She had an old school Dayton Sewing Machine Conversion Kit installed ( 1/15hp, 115 Volts AS-DC) Model 2X420. Seems like Dayton may have gone out of business. Are there other options to procure another motor kit? I saw some online such as this, but want to ensure I'm buying the right one. Thanks so much.
