Review on Spectra Premium FD32S Camshaft Synchronizer for Ford, Mercury, and Mazda Models - New & Improved! by Jonathan Self

No instructions in the box just the parts you need. Installed on my 2000 Mazda B3000, Volcan 3.0L flex fuel 6 cylinder engine. I used the Ford Ranger forum to help with the installation with a simple method without putting cylinder 1 at top dead center. Just remember to take a few shots before you take the old one off and align the new one in the same spot. The top rotates, so look for the only part sticking out in the center circle. This method didn't require me to use the align tool.
