Sorry, I don't have the number handy. I ordered a new pair myself and they are on back-order, so evidently everybody took my advice and bought up the available stock of these.
Plato is correct: I did not have to bend or cut any loops on my 1500. I just slide all the available slack forward through them. Then I pull the swingarm back just enough to unhook the shaft, propping the back end on jackstands (or you can hang it with a little rope.) Tip the front of the swingarm down, and slide the shaft out forward and down. just clearing the underside of the left engine case and floorboard.
As for the final drive oil, I think almost every one of these has leaked out the front seal because the factory overfills the oil. When you re-fill the gear oil, leave the bike on the side stand instead of standing it straight up. This will reduce the volume of oil so it doesn't "drown" the front seal. This will eliminate about 99% of the leakage problems.
Since you need to check that oil at (at least!) every engine oil change to see if it leaked out, I just change it each time I change the engine oil. It's cheap, and once you get the bag off and get down on the ground with tools and a rag, you might as well change it anyway.
