Knee pin help

[Psychoboys]

Can someone point me to some guides on how to replace knee joint pins in vintage 12" Mego figures? I'd like some video or pictured guides, if possible. I've never attempted anything like this before. I'm going to attempt to repair some bad knees on some vintage KISS Megos. Thanks guys.

I recently needed to do this myself and was having difficulties getting the pins to connect and stay connected.
After a few failed atrempts using pliers, I had to get creative. I looked through my sockets to find two that would fit in the holes of the legs while the pin and holder are in the leg.
Next, I took a pair of vice pliers and squeezed them helping the pins to pop in and connect.
This may need the help of another, as my wife assisted holding the sockets around the leg so I can get the pliers around and give a good squeeze.
Hope it works for you
