Even though the bases for these valves have been discontinued, we still have an inventory of Mark 40 single solenoid and double solenoid valves.  We also have available a kit Part # AOS55-40-P for $129  that will allow you to attach the new Mark 55 valve your old Mark 40 manifolds so you don't need to replumb the fixture!  The AOS55-40-P kit is 1.19" thick (the same thickness as a speed control sandwich) and has an integrated MK55 Plug to make the electrical connection to the new Mark 55 valve.
