APT 188 Report post Posted October 1, 2010 Hey guys one of the things i have to get done for my cert is change my gearbox and engine mount Nuts to self locking nuts. Would anyone be able to tell me the sizes of these ? and also whether its fat or narrow thread- as i don't have my E30 with me at the moment. Thanks Guys Quote Share this post Link to post Share on other sites
