Thanks for all the good info on this. I reckon I will keep my eye out for a more 'assembly line' part.
I'll keep watch on the eBay part anyway.
BTW, how does one go about pulling apart the ring that the cable attaches to? Is one side better to open then the other?
Being that they are spring loaded, I don't want to damage them. Or were they made with the cable attached already??
Thanks
