My understanding from reading the report is that due to it's un-lifed nature the part wasn't tracked so no one can actually answer that question, or indeed where other ones from the RAF fleet may have got to. Bell considered the visual inspection interval would catch any cracks before they propagated to failure so it wasn't thought to be a problem.
There is a recommendation to find out where the parts have got to, which as pretty much any 412 serviced by Bristow could have received a MRG SC that had been used at DHFS seems like a good idea.
