My new water pump from TRF doesn't fit. The three mounting holes do not line up. The old pump came off easily and goes back on just as easily . The old pump has PC11A in the casting, the new one has LUCAS in its casting and the sticker on the box says made in Taiwan. . Visually, it looks the same. I called TRF's service number and was given a tech dept. number to call, but no one answers. I have dealt with TRF since Charles began his business and have always received good products and good service; I hope this is an anomaly.
