I have a couple of the 134 screw on adapters because everybody's after me to fix car AC systems all the time. A guy I do a lot of HVAC work with wanted me to help him with his daughter's Honda AC. The dealer quoted $4,000.00, we repaired it for substantially less money. I had never worked on a Honda AC before and had to look it up on The Web to see how it was put together. The defective expansion valve was behind the glove box so we had to remove half the dash to get to it. A new expansion valve was $13.00, a receiver was less than $30.00, some oil and 134a was another $30.00. I think we beat the dealer price. It took an afternoon but it was worth it to do it right.
