Univair and Aircraft Spruce have them. I'm sure others here could share additional sources. Air Repair in Mississippi probably also has them. As it turned out I didn't get a chance to make an order today so I may check Air Repair's price before I order.

62C was in the same spot - I could find no record of the main spring being replaced, so I asked my shop to replace the entire assembly two months ago when the baffles were replaced. They sourced the springs from Aircraft Spruce. Good peace of mind moving forward ...

Aircraft Spruce re-markets them, made by Univair under FAA/PMA. The mainspring is the only one of the "stack" that receives wear of concern, so replacing only the mail spring is my recommendation for most: https://www.aircraftspruce.com/catalog/ ... ckkey=9943
