Initially, it took quite a long time for the part to arrive due to it being on backorder. Not the fault of SPD but a bit annoying. The part was almost exactly a perfect match for replacement. All of the mounting aligned perfectly. The part was the same overall dimensions. The only quirk to be aware of is that they moved the connection points to the electrical from the version I had. Luckily, I was able to dislodge the quick connects from the existing plastic head to allow the electrical connections to still be made without having to rewire. If you experience this as well, carefully breaking away the plastic wire harness should get you access to the quick connect without damaging the wiring. I also had to reuse the drive spacer from the previous version but this didn't seem to be an issue. You might consider going ahead and buying the spacer as it appears this is a separate part not included in with the purchase of the motor.
