Top Secret 2 Report post Posted January 28, 2010 Check to see if it is the same size as the gearbox drain and fill plug. If it is, then it's a 17mm hex. You should be able to pick up sockets at repco Quote Share this post Link to post Share on other sites

BM WORLD 1283 Report post Posted January 28, 2010 use a bolt head that fits in then screw 2 more nuts on to it to lock them , you can then use a spanner or socket on the end Quote Share this post Link to post Share on other sites
