If you have a spare one of these:
For goodness sakes hold onto it. It has taken me over a month to source a replacement, which was a bloke from the club. They come in the XL650 spare parts kit and can be bought from few places, or gotten for free from Dillon USA as a warranty replacement free of charge. Saffire Trading in Oakleigh Victoria has some on the way, as does NVT Australia.
Stay tuned for a test and review of a solid aluminium one I ordered due to arrive in a couple weeks. Cleavers are OOS as well and due in a month.
Also, the XL750 is totally INCOMPATIBLE. Ask me how I know.
For sale: 1 XL750 indexing ring. $20 delivered.
