Need more length

Hello,

As you can see, I purchased the S140-10 quick tilt single. I ambwriting because I need to order 2 5 pounds of similar nature and 2 2 pounds of a similar nature. However, I need the coil to extend with constant force up to 32 inches. The one I have does not extend to that length. If possible, I would like for it to be similar in size or smaller with the requested constant force pull.

Is this possible?

Tha k you.
