Took this off the rear wheel of a 78 FXE that had been sitting for some time. Can someone tell me if this is OEM for my year and model.

Inside edge of rime says "Firestone"

Valve stem hole markings

Abut 3-o'clock postion on valve stem side of rim

About 7-o'clock position on valve stem side of rim

And, if not correct can someone post a pic of the correct rim and markings if you have it please.
