I have a 2008 Prius needing new ABS brake actuator. I have the old one out and it is part number 44510-47050. The car has over 200k miles and I'm hesitant to put in a new unit with prices of $1,200 to $1,800, so I'm searching for a used one. My understanding is the new revised updated Toyota abs actuator has part number 44510-47051. Anyone been down this path before, and if so, where did you procure your used unit? Thanks in advance.
