Old-fashioned remedies for piston slap when finances prohibited a proper rebuild: (1) knurling the skirt on the thrust face to expand the diameter of the skirt, and (2) install a piston expander. Both were capable of providing some short-lived relief, I did both myself many years ago. Plenty of descriptions of needed tools and materials in older editions of service manuals such as Glenn's.

A skirt expander is just that, a spring steel device inserted into the piston from below which exerts an outward, stretching force on the skirt.

If you need illustrations I can provide some from Glenn's Manual.
