Hi RC777 !
And, if you have die, It's easy to make the thread yourself too !
I do mine and it take about 10 min.
You only need die M2.5 x .45
You have to grind the end of the rod at 45 degré.
and pass the die on the rod.
After, all work # 1.
Don't try to put your plastic link on the rod before do that. You can ruine your plastic link !
Thank's !
