How do I replace these metal pieces from my instrument panel?

20200122_110218.jpg
found one problem on the left side///broken power feed pins on the circuit board
used solid copper buzz wire pre tinned everything// used a fiberglass pen to clean everything //soldered everything //checked , bulbs and board for continuity //cut pigtails off of the back,used a dremel tool to sand the backs of the pins flush with the board an a piece of gorilla tape on the back to keep the back from shorting out on the cluster frame.

stronger than factory !!!!!!

I tried to solder this wire to the old metal piece like you did in the photo, but the solder won't stick. Is there a certain type of solder or copper wire I need to buy?
