If you have a broken plunger/linkage, you can repair it and replace the broken part for a lot cheaper. Sometimes you can’t find complete linkages but you can get the individual parts or the linkages. Here’s how you can build them, or repair them. It’s been awhile since I did this so I had to refresh my memory of how I did it.
