Here's a pic of the sleeve/bushing and the seam you need to split/spread in order to slide it over the threaded end. Also attached is the actual bump stop before cutting (which is cut quite easily with a utility knife).
Niko, if you wouldn't mind, feel free to insert these images upstream so folks don't have to read through four pages of posts

Thanks for a great write up by the way. I took the easy way out and paid to have it done.
