I'm assuming you have an R/T Charger (I guess the "8" was a typo). The swap's a bolt-in deal, so-to-speak. But, to do the swap, you'll need front and rear suspension spindles, brake rotors, calipers, pads, misc hardware (bolts, nuts, clips, etc) and possibly wheel hubs and brake lines, too. I'm not sure what differences there may be between the R/T and SRT8, in the ABS/Traction control systems, either. You would probably have to deal with a salvage supplier to get everything you need. Cleveland Pick-A-Part sometimes has deals on complete packages..
