Easy repair
I snapped the locking lever. Ordered parts before opening it up and swing what I needed. Ordered this and a couple more parts due to being cheap and I’m sure they were getting wore out due to the temporary fix I made to make it work with a broken lock lever. Awesome site. Great price on parts. Easy to read manuals. Will use this site more often
