If you're going to the trouble of crimping on a new terminal just crimp on a Male Packard 56 or 59 and eliminate the extra connection... IIRC the 12ga power wire is a 59 terminal but don't quote me on it.
The bulkhead studs are a great place to connect with common ring terminals and a fusible link.
