The original socket is a BGA (ball grid array) style device, so very difficult to fit the same kind of socket.
I've repaired a number of the 68060 sockets on the Cyberstorm mk3 boards by removing the existing socket using SMD hot air rework tools and "making" a new socket out of
single pin sockets.
A little time consuming and you need very good soldering skills to be able to do it correctly. But it works well and any solder joint problems are obvious.
