My experience with March was "deal with it!" I wanted a stock set of pulleys, their setups for a 460 either overdrive your water pump or under drive your alternator. For the prices they charge I would think they would try to be a little friendlier too. Most Part makers in the industry have bent backwards to help me along the way on my truck build, but I would agree March is a bottom dweller. The problem is there are very few aftermarket pulley makers, so I guess they can sqeeze by with poor customer service. I've got march alternator brackets so I guess I have to be gratefull that they even make those!
