Suspension & Brakes - Need help ---Sway bar end links????

Okay I have a 94 camaro z28 m6. Recently bought a used moser 9". The guy also gave me a rear sphon sway bar. I did not get the end links. I happen to look at the jegs catalog and they sell them in different sizes. Does anybody know what size I need to buy. Also do I measure the diameter of the sway bar to find out what size I have?

I don't know how valid this method is, but here is what Energy Suspension recommends (bottom of the page):
