I've recently become an Eichler owner and am in the early stages of renovation. I'm going to upgrade all the original sliders with double glazed replacements. Two of them that were in the bathrooms are frosted glass. There are nine in total. I can provide the measurements if you're interetsed. All all operable and appear to be in good condition for their age. Please contact me if you're interested. They're in Los Altos.
