Winchester 100 trigger assembly

[fredo]

Gents, wanting to help a friend with an older rifle, Win 100, .308.
Trigger was froze up, so I disassembled, cleaned it up. Looks like it needs a new safety kit, and trigger spring, the other parts seem ok?
Also, I've read that firing pin needs replaced, due to an older recall?

Question is, can anyone recommend a gunsmith familiar with this trigger group? Wouldn't mind sending it off, and making sure it's done correctly...

Thanks for help!
