Review on iiwey 4-Pack Replacement Joystick for Nintendo Switch Joy-Con - 3D Analog Thumb Stick, Includes 2 Pack Metal Latch and Y1.5 Original Screwdrivers, Fixes Drift - Replacement for Switch Joycon Joystick by Rory Stice

BUT once you get there you can find out. Be especially careful with wafer-thin ribbon cables. I wouldn't bother swapping out the "locking pins" on joy refills. I made the mistake of replacing one and I think the spring was installed incorrectly and the joycon was stuck in the switch. I had to disassemble the joycon to remove it from the switch. Peter!
