Pulleys
The tensioner pulley was a little too wide so had to grind it down so that it would not scrap on the motor other then that was ok.

Serpentine belt tensioner assembly
Correct part for my application, great price compared to a dealership, fit, easy install, my OEM pulley was blown and buying the whole assembly was only a little more than buying just the pulley

Easy replacement
This was an easy fix and the video they provided was a huge help! Part looked just as good as the factory ford part and fit like a glove! Thanks again A1 auto for saving me the trip to the mechanix shop.
