Where abouts in MA are you located? The main place that deals with S-chassis and parts is CIPmotorsports in CT south of New Haven. Depending on what your looking to have done or if its just as simple as advice or a look over I can help you out. Im located outside of springfield and yeah I don't own a 240 shop but Ive been dealing with SR's for over 8 years and have plenty of experience to put you in the right direction with parts and performance.
