How do you replace tailgate lift rods?

I did two of these jobs last month.The replacement shocks I got just bolted on very much like the originals on the top side and cliped on the bottom. Removeing the old one is a little tricky figering out how to flip the little spring clip up then pull it out then pop the shock off.Have somebody to hold the gate up for you while you work it is much safer than a prop rod.
