Technically it's still fixing them as they're restoring function that was otherwise unwearable. You can also consider them as an enhancement to remove an inherent design flaw. Half x 1.1 if you like!I would consider that "fixing" them only if they were returned to their full, original functionality, i.e. the same spring hinges they were before.
What he's doing I would call modifying them to traditional-style hinges.
But it's just semantics, really...
I had a handful of spare oem hinges and those were used up quick in my earlier repairs. Some broken oem hinges can be fixed and reused depending on how it's broken. Both latter scenarios yield oem spring hinges and are "repaired with genuine parts".
