Hi mate, yeah I welded around the lobes on my locking tool to reenforce it,unfortunately never got to finding out if it was good enough as the bolt rounded 😂 thank you for confirming the genuine part being INA, awaiting my INA one to come so I can then drill the bolt out, replace adjuster and rings again and fingers crossed be job done 👌🏻 it’s all fun and games isn’t it 😂
