Got an exact fit/part at less than half the price my local shop quoted for this unit. Went in the tight spot and by me doing the work, I saved well over $100 verses my shop doing it. Thanks!
The part was just right. The mechanic who installed it was impressed with the quality and what it cost me as well. The only problem was that it took 8 days from the moment I ordered it for the part to arrive.
