Marc, If SS bolts arn't good for the aluminum, then what would be the best. Just regular high grade bolts 10.9, higher than what's in the car and maby plate them. I have access to all the bolts and have parts plated by a shop close to me. I can get 7mm bolts from full thread 12mm long to partial thread up to 70 mm long. I just need to know the size needed.
