Awning gas struts (spring)

[Quiroule]

I need to repalce the gas struts on my 20 feet awning, does anyone know what rating they should be. They go from 24 to 150 pounds.

Here is what is stamped on it:

TUSON 0949
3108392 139

The tube is about 16 inches long.

Thanks

Not to high jack your thread but I need to replace mine they make terrible shudder noise when bringing in awning. What's the best way to replace them I can't find any info online.
