Ok, assuming the leads are inline?   Remove the original through hole
leads, replace them with plug in socket leads, individual, assuming
sufficient lead length on the original component, straighten the leads
to the plane in which the component is mounted, plug into the socket and
solder, you could also use a bifurcated terminal as an attachment
socket.    Check in Keystone Electronics catalog for wire wrap terminals
for leaded components and see what they have.    I have seen a pitch
fork (three tines) that are separated slightly style.
