Im going to order my new rack tomorrow.. they want charge diff price and have diff core charges for each year, anyone know why if its the same part ? ? or do they just hope you will buy the more espensive one ? the 2 cheapested years are 2004 and 2008 to order.. 05 06 and 07 are the most... thanks, if nobody does a write up I guess Ill end up taking some pics... also any other ideas on what should be replaced while im down there ? gunna do shocks most likely..
