I don't know if this will fix it but I have access to a couple of
broken C64s that may fit the bill.

This text file describes what to do in order to fix Amiga 500(if one
of the CIA's is dead) with the parts taken from broken Commodore 64.
I SHALL STATE THAT THIS IS A HACK, ITS A HACK! ITS A HACK!!! HOWEVER CONFIRMED, IT WORKS FOR ME.
In C 64 there are also two CIA's and they are at (locations according
to new pcb) U1 and U2 they have printed 6526B on them. So now you just need to desolder one of them or both, clean up the pins and put in your Amiga in place of B one. The pinouts are same so nothing can go wrong.
There are several mothods to strip the chip from pcb. I used ordinary soldering iron and the simple sucking device to pick the tin. If you
got no such tools then you may use simple handy gas burner directly on
the pins from some distance. But before doing this set the nozzle not
to cut but to distribute the heat smoothly. Then try to toggle the
burner form one side to another and if you notice tin melting grab the
ic - be cautious its hot! Also, dont heat the chip too long!
