Just wanted to update my review. I ordered an OEM Lexus pump and had the same problem. Maybe it's my car. I gave 4 stars because I was able to return the item. and get my refund very quickly - part does not fit 2007 Lexus ES350. The section width for the bolt through holes is too wide, about 63.5mm. The part that detached from the car measured 62.7mm. return part
