Ok I did something stupid... motherboard edge connector

I was replacing the 72 pin connector on my front loader NES and I decided to clean the motherboard connection.

(I had already put the connector on but games were still having an issue.)

A couple of the brass leads came off.

How do you go about replacing edge connector leads?

And incase you lost one (let's just say I lost one), where to get a replacement piece.

Yes I could send it away to a service. I would like to know how to do it.

Thanks in advance!

After seeing the board I realize I was trying something else. I think I was trying to add metal to the contacts, but my iron was too hot.

Is there lead tape?

Here is the connector ( I forgot you could add photos).
