Sign up your license with the CFLC and request an authorization to ship to an 01 FFL who is also signed up with the CFLC. Ship the authorization letter with the receiving FFL license. It's really simple. Done it many times.
To ship to 03 FFL in Cali, just get a copy of his license AND his Certificate of Eligibility (COE). Ship away! Done it a couple times. Also very easy.
