As noted by the feedback left by others here, absolutely incredible service provided by Shannon, Lori, and everyone else at Cluster Fix.
The speedometer and oil gauge in my 2005 Trailblazer cluster went haywire, and as a result I was in need of a repair. With the help of Shannon's video I pulled the cluster on a Sunday, and mailed it in Monday morning.
Remarkably, the cluster arrived back home on Saturday morning, and an hour after its arrival the cluster was reinstalled in my vehicle and the dash bezel back in place.
North Carolina to Washington to North Carolina in less than a week!
The entire process was far easier than I expected, and as a result I highly recommend Cluster Fix.
