The website name is up for sale and there is no phone number just an address. I managed to search and find a number 250-658-2590. Good chance they're out of business.
Done a search of some sources I have and website of oddball manuals and I have found nothing.

It involves the removal of the rear section of the motorcycle.
Fitting the new swingarm onto the bike.
Fitting the axle and drive line.

Taking a test ride after checking to make sure it tracks right, no strange noise or vibration.
Fitting the body prior to painting, making sure the lights work.
