These have been in a warehouse and speed shop since the mid 90's still wrapped in plastic. We opened them to check length and condition. They do have what looks like a very small amount of surface rust towards the ends as seen in the pictures. These were a high quality pushrod at the time of manufacture and made in the U.S.A . 

Set of 16 new old stock Erson E917011 chrome moly pushrods. These are 5/16 diameter and I get 8.6575 for length on my cheap calipers. These are not case hardened so not intended for use with guide plates.

Application shows 61-66 Pontiac 389 and 421. If you have a 67 and newer head on your engine they will not work.

As of July 9th USPS has combined all non priority shipping including First Class into 1 service called Ground Advantage. Any listings that state we ship First Class will now be shipping Ground Advantage. Ebay is supposed to be updating this in the shipping section of the listing however to avoid any confusion if our description states First Class there is no more First Class available. They are telling us standard delivery times will stay between 3-5 to most locations as before however we have no control over these changes. Ebay will also be updating expected delivery dates if there are any changes there.
