The extended studs included in my H&R kit don't seem to be the same part number anymore and I am having trouble locating replacements they are 40mm thread length. Any help or info is appreciated. one of my extended studs was threaded when I put them on and it wouldn't hurt to have a few extra replacements for down the line. part # for the studs is 1254044. The kit was 10mm btw I don't know why it says 20mm on the label.
