Quoted from ejacques:I'll chime in....looking for a complete head for Williams Gay 90s (back glasses too) and a head for a Gottlieb Jet Spin. (I've got the backglass and guts, the head was waterlogged though).
FWIW, there's an entire Gay 90s for sale on CL here in San Antonio for $500. Maybe you could work a deal for the whole machine.
