Dear Mr. Eller,
Thank you for posting your request on History Hub!
A copy of your DD-214 should be in your Official Military Personnel Files (OMPF). OMPFs for those who served in the U.S. Army after November 1, 1912 and prior to September 30, 2002 are in the custody of NARA’s National Personnel Records Center in St. Louis. You can order your OMPF online, by fax, or by mail. You may request your entire file or just your DD-214. For more information see Request Your Military Service Records.
U.S. military personnel tested before September 1974 can request their USAFI/GED Transcripts through https://jst.doded.mil/usafi/
We hope this information is helpful.
