I've found some of the information I am looking for, but not all of it. I know that the 9c impala fleet cars have a front strut tower brace, boxed rear trailing arms, thicker sway bars, and front brakes are 1 inch larger. WHat I haven't been able to find out is exactly what years this stuff comes off of. Some sources say only 00-03 will fit '00 cars. Others say 00-06. I'm also trying to find out if these fleet cars had better springs and struts than the gtp. A junkyard swap sticky or section would be a great addition to this website. I have a 4 day weekend coming up so I'd like to get to the junkyards and get this stuff before the weather gets bad. Thanks for the help.
