Schucks and napa had 17345 as the part number, way too small. Ended up with napa part #9350. Fits great, easy to get on and the tensioner is midway through it's range, but now the compressor is noisy so probably needs a rebuild. Suppose I should expect that after it sitting for 3 years. <img src="/forums/images/graemlins/shiner.gif" alt="" />
