edbar 6 Posted April 27, 2011 Going to remove the sunroof this week and need to get some alloy plate to do so, is there a minimum thickness required to go sprinting by the msa? I have looked in the blue book but cant find a mention? Thanks Edd Share this post Link to post Share on other sites
philfingers 5 Posted May 5, 2011 i think steel maybe a requirement. you'd be best looking on britishrally (google it!) forum and asking there Share this post Link to post Share on other sites
