Hey guys, I'm having a very difficult time trying to figure out what clutch I need in my 2009 dodge challenger r/t. The dealer gives me a part number that shows a single disk setup for my vin. The auto parts stores say it's a double clutch disk setup as well as mechanic with my vin. My question is who is right? What in the vin deciphers a single or double, will production date help? I want a spec clutch and they say double. Please help, thank you!
