Worked Perfectly!!!

When you go to order these just make sure that you buy the bolt set that is recommended for purchase at the same time. As it states in the description, these pulleys are quality built a little thicker than the usual so you will need the longer bolts for the pulley that attaches to the harmonic balancer. These look great on my 66' Chevy C-10 and work wonderfully. I am currently only running a mechanical fan and alternator but I love that this pulley set has the additional groove so that I can add power steering in the near future. Additionally, the fan pulley conveniently comes with both 1.75 and 2.25 bolt holes for the different sized fans/spacers. Thanks Speedway.

Precision

Used this product on my dirt oval El Camino. We had problems throwing belts with the stock pulley system. This system bolted up perfectly with no spacers needed and even removed one of the supplied belts to keep the factory power steering. This kit took about 15 minutes to install. Super happy with the results.
