Proper Seat Belt Bolts

Does anyone know what the proper seat bolts should be in my bucket seat 70 Dart Swinger? Are they all C-10s, or is there a mixture of styles?
The ones I have right now are all mismatched and Id like to have a proper set.
Thanks FABO!
Edit: I just found this old post by @72bluNblu , it would be my guess that it is the same for a 70?
