Went to change plugs and tube seals on my 73 swinger ......no tubes! My manual shows there should be tubes. Any quick visuals to tell what year motor is in this ride?

From “[url=http://www.allpar.com/fix/spark-plug-tubes.html]ALPAR[/url]â€￾:

Referred to as, “Peanut Headâ€￾, there are several renditions of this casting that involve pollution control equipment. Some of these heads contain passages for exhaust gas recirculation, some don’t.

Someone either swapped your engine for a later one, or just changed out its head. By looking up [url=http://www.mymopar.com/index.php?pid=31] casting numbers[/url] of your block, & head (must remove valve cover to see number) you can figure it all out.
