There would only be a serial number change if there's a new frame. If it's the repaired gun same serial number there certainly shouldn't be any 25 bucks for sure no 10 day waiting period.
I'm sure they will want the whole gun to make sure everything is proper but doesn't sound like a new frame would be needed.
I'm sorry you live in California. I'd for sure mention your concerns with them prior to shipping. They may be required to return it to the address it was sent from. If such is the case send it from work or someplace where you know someone is around all the time.
