Can anyone who has the series 7 trim assist spring system please let me know the spring measurements and wire size please.

My plane is a Series 5, but I can't imagine there would be any difference in the springs supplied for Series 5, 6 or 7 assist kits. Perhaps someone with a Series 7 can confirm similar measurements.

The overall length of the spring is 5.25". The coil section, excluding the end hooks, measures 3.875" long and 0.75" in diameter. The wire measures 0.107" in diameter.
