Thrustmaster Top Gun potentiometers

I have an old (original) Top Gun Afterburner HOTAS that I was going to give to a friend that just got his first PC. The pots in it are old and crusty. Two of them are broken. Any ideas where I can find them? It’s just a quick 10 minute solder job to see if MSFS is for him.
Thanks
