I am not 100% certain but I think the Countach, Diablo and Murcielago *MAY* be the same. You'll need to do some digging for sure.Here is some info on the OEM Countach part: http://www.eurospares.co.uk/partTable.asp?M=2&Mo=656&A=2&B=38016&S=Some of the correct Mercedes models for the Murci are listed here: Off-the-Shelf Parts for the MurcielagoHere are some I got for my mine: http://lamboclone.com/index.php?topic=1516.msg15131#msg15131All of that aside, with a little ingenuity, you can make a lot of stuff work. it really depends on how picky you are about that exact OEM look.
