Replacement follower and springs for U9-35 magazines

I have recently opened my magazines to clean up carbon dirty on them, and noticed that my springs have a slight orange rust on them. This got me concerned since geting replacement magazines might not be easy for me. Does someone knows where can I get replacement springs for these magazines? Also, one of my followers was slightly damaged by a bolt(lockback was broken, fixed now), and I would like to get one or two extra ones…
Should I contact psa support directly?

Contact PSA but i dont know if they have extras. THRIL makes those mags but not sure if they would provide parts or not.
