I am looking for a replacement mechanism to hold a door shut and or the replacement spring to make this work again.

Plate is 5.5 inches long and one inch wide
locking bay 3 and 1/8th wide 3 and 5/8 tall and half inch thick

The broken spring is half an inch spring body(the coiled part) and two quarter inch circles on either side.

Thanks for posting. I don't think we would be able to replace the spring. The closest replacement I was able to find was our 42-009 handle set. Compare the measurements to see if this can work as a replacement.
