Small Block Chevrolet - Gen III/IV - LSA

If you're looking to swap an LSA or LS engine into your vehicle but your engine didn't come with an alternator bracket or the factory setup is too wide to fit your project, Holley has the answer. The 20-166 Bracket tucks the Alternator in closer toward the engine when compared to the original LSA accessories, giving more clearance where needed. These brackets look truly at home on the LSA engine, so much so that nobody will realize it didn't come from factory this way.

NOTES: Torque M10 bolt to 36 ft./lbs. When wiring the alternator, install the included 197-400 plug into the alternator. Next, connect the yellow wire to switched voltage that is "on" when the key is in the run position. If the vehicle has a "charge indicator light", the yellow wire can be connected to that circuit.

Asurion worked as intended.
After three years, my monitor failed. Asurion paid to send it to a repair center. I didn't save the box the monitor came in, and paid $23 to have it packaged up. They kept me informed of the various steps, such as en route, arrived, testing, and repair started. They discovered it could not economically be repaired and refunded my purchase price. The entire process from me telling them it was broken until the refund took 5 days. I am well satisfied with the service.

Great value - functions well with fairly easy setup.
I found the setup to be fairly simple. It performs exactly as I hoped. I needed a printer, copier and scanner - it is a great value. I did have to do some research to complete the scanner setup - that could have been easier overall.
