Piston skirt expanders

[Brian T]

I see while searching here and see that some of you have come across piston skirt expanders, I have those old antique split skirt pistons that haven't been sold since who knows when, my #2 has a louder than I like slap, I have no blow by, and no problem with the cylinder walls.
I am biding time for other engine work, -- If .90 over pistons were available I would replace them, I have never seen these expanders for sale, if someone has 4 they do not want please let me know.
Thanks in advance.
