Side door latch/lock won't close without assist...

Pot metal is just a Zinc alloy and is very brittle and beaks easily especially with constant door slamming. My MH is a 1996 so mine has broken several times. Instead of buying a new one that may or may not be steel I just made a steel splice that joined the two broken pieces together so far after 5 or 6 years it is still holding up. Yes, a magnet will stick to steel but not to the Zinc alloy.
