I would call Phil(top of the main screen"buy parts") Great guy and he will be able to get you all the parts and info you need. Seeing no one else has said it yet AVOID THE DEALER. Same parts twice as much.
More info needed though. How long have you had the car? Miles? what have you done so far in the way of maint?
Best of luck, when the bugs are worked out these are great cars. Especially the SDL best I might be a little biased!
