The unit appears to be complete, but it probably doesn&#8217;t work.. and I guess it doesn&#8217;t even matter. Even when they were brand new they apparently didn&#8217;t work worth beans, so there is little point to it. It&#8217;s cool to have anyway! Installing just the Phototube &#8220;eye&#8221;&#8230; the part mounted to the dash without having the rest wouldn&#8217;t be kosher&#8230; that would make me a poser. To earn the bragging rights associated with a rare accessory like this, ya gotta have the whole thing, even the parts you don&#8217;t see. It obviously needs restoration and a new rubber gasket, but it should be pretty neat to have on the car. Should be a conversation piece, as many people don&#8217;t know what these are.<\/p>\n\n\n\n<p><a href=\"http:\/\/rover.ebay.com\/rover\/1\/711-53200-19255-0\/1?type=4&amp;campid=5335809012&amp;toolid=10001&amp;customid=1960car&amp;mpre=http%3A\/\/search-desc.ebay.com\/search\/search.dll?query=(autronic%20eye),(guide-matic)\" target=\"_blank\" rel=\"noopener\">Find a Guide-Matic or Autronic Eye for your car on eBay!<\/a><\/p>\n\n\n\n<div class=\"wp-block-image\"><figure class=\"aligncenter\"><a href=\"https:\/\/www.60impala.com\/blog\/wp-content\/uploads\/2011\/02\/Capture.jpg\"><img loading=\"lazy\" decoding=\"async\" width=\"796\" height=\"601\" src=\"https:\/\/www.60impala.com\/blog\/wp-content\/uploads\/2011\/02\/Capture.jpg\" alt=\"1960 Guide-Matic\" class=\"wp-image-327\" srcset=\"https:\/\/www.60impala.com\/blog\/wp-content\/uploads\/2011\/02\/Capture.jpg 796w, https:\/\/www.60impala.com\/blog\/wp-content\/uploads\/2011\/02\/Capture-300x226.jpg 300w\" sizes=\"auto, (max-width: 796px) 100vw, 796px\" \/><\/a><figcaption>1960 Guide-Matic<\/figcaption><\/figure><\/div>\n\n\n\n<p>According to an article posted in various places on the web by John Oldenburg, a veteran at restoring Guide-Matic and Autronic Eye&#8217;s, these units were very specific to each vehicle and year that they were installed, even though many of them may look very similar.
