That valve is 100% mechanical, unless it is all rotted away, you can fix/solder/weld/fab to fix if you don't want to spend $75. or at least try. Don't think you need the temperature tube. It does not have to end up looking exactly like the orig after you fix it, just mounting and cable and hose attachments. Ebay has them sometimes. 55-59 are the same no special one for 59.
Right is right, even if everyone is against it, and wrong is wrong, even if everyone is for it. - William Penn
