i broke my clutch cover today landing on a rock. i saw it as soon as i got airborne - i tried to miss it right but i hit it just under my rear brake. i think it just broke the cover - no damage to engine block. it did bend the hell out of the bottom bolt that hold the cover on. i knew i did damage b/c the motor sounds funny. so my questions are what should i replace it with (stock or aftermarket part) and should i be concerned about internal damage? thanks in advance!
