Cobra trailer stuck closed

On a Cobra trailer for Duo Discus, I used a hoist in a hangar to the handles then ran a sling under the lid (heavy ratchet straps, could be adjusted to take the weight off the handles) while replacing a dead strut. Yes, heavy and above a height you'd want to lift to.
Requires pulling the wing out to easily access the hardware and remove/replace the strut.
Initially one strut had failed on this trailer, two were purchased but only one replaced. Suggest that if one strut fails, replace both as soon as you can.
This job is easy with the right tools.
The rod ends from the original struts may be needed for the new ones.
