You might find the force printed on the side of the strut. I had to replace
the front door struts on my LAK-T5 trailer. The original parts would have
had to be ordered from Sweden at a cost of, IIRC, 132 Euros each plus
shipping!!!

I called one a gas strut manufacturer in the US and the lady I spoke with
had me read the label on the strut. In one string of characters was the
group: N100 (I think). She told me that was 100 Newtons or 22 pounds
force. She couldn't provide what I needed so I measured carefully and went
online to the McMaster-Carr catalog where I found replacements (25 lb force)
for $40 each. They had smaller eyes on the ends but it was simple to make
new mounts.

BTW, they work just fine.

I have the last Std. Cirrius made by Jastreb/VTC. It came in an Eberle
tariler however the tougue is not Eberle. I need to replace the gas
strut.
The gas strut is a stering damper type and looks like the gas srtut they
put on cars to open rear doors and lift front hoods. It is not the auto
suspension shock type. I cannot find a gas strut with the right size. I
am
not sure what force I should get either. The rod end has threads that are
M8 1.0. Anyone have experience with this.
