Challenger Fans, If you have puchased any parts for your new challenger and they didn't fit--or--fit correctly,please be specific and POST here!! example--I bought a SLP dampner for my 5.7 hemi-(2009) the dampner will fit the 5.7---2004-2008 and 6.1 hemi 2009--BUT WILL NOT fit the 5.7 hemi 2009--evidently the engine in the 2009 hemi 5.7 is different and the 25% under pulley IS NOT AVAILABLE yet according to TECH at SLP company. I didn't find this out until a bunch of work and time was spent taking off the stock dampner and noticing the visual difference. If any of you have a similar experience--please share--maybe we can save fellow members some headaches
