Ok I got a used exedy twin disc for my lsvtec hydro trans. about to put it on. On the two disc there is one side that's flat and the other with a hump on it. I have no idea if the flat side of the Clutch disc should be facing the flywheel side or pressure plate side. Please give me input i already dropped the tranny just need to find out asap. I want to get it done tonight. Thanks

 

Anyone?
