I want to say it was around 30in, I know I measured all of them but don't know where I left said measurements... unfortunately.Did you measure the front part of the driveshaft you used ? i bought one of a 2002 6 speed c230 coupe its 29 in from end to where the rubber flex plate bolts to the shaft. ill be working on my 2004 clk500 i did a rough measurement a while back came up with around 30-31 in , i need to get back under there now that i have this shaft to physically compare.
