I went round and round trying to locate these Aft Lift Strut, Ball Stud Mounts onto the F-721 Side canopy Decks. The plans give dimensions but it was difficult to actually measure. Image 1 shows how I was able to look through the Ball Stud Hole to see the ruler dimension for the required 9/16” off the canopy Deck. I used double side tape for initial placement. Then clamped and drilled.
