Many of you know I recently ordered a serp belt pulley and bracket set for my 408W. In short, the folks at CVF got everything right !! My order shipped quickly and packaged very well in foam wrap and individual boxes. The billet pulleys and bracket quality is superb. And each item comes with clear, color installation instructions and top grade hardware. Of course each pulley must be spaced for your application but that would be the case with any brand. I bought a Saginaw power steering pump from another vendor and the pulley and brackets fit up great. Lastly, I phone ordered their A/C compressor (in natural finish) and when it arrived it was polished. When I alerted them via email of the error, they quickly sent me a natural compressor and a return label for the polished compressor. And I sent back one of the belts that I couldn't get to fit for a refund and no questions asked. If youre looking at a serp belt conversion for your Mustang, CVF has the best prices of all the vendors I looked at and you don't have to buy all the accessories from them if you don't want to which keeps the price down.
