thanks for the informationI have these fitted to the same model.
I was unable to remove the standard in-bar anchor for the end-weights. The You Tube videos for this task were for the older models, did not work for the newer model. I spent hours on this and eventually gave up.
I left the in-bar anchors in and fitted the Barkbusters at the end of the end-weights. This required some modification to get it to fit nicely.
If you can get the standard in-bar anchors out, you should not have a problem.
