I was going to do the exact same thing. The plan worked if you replace the metal plate with a soft shackle,or a duth clip. The soft shackle works well with a cloth covered washer that your spreader bar tip can go through to protect your cordage.
Works the same with a dutch clip ,but grind a spot for the spring closure on the dutch clip off the washer to prevent pressure on the clip closure. I made the choice to not use the spindrift as it wasnt for me,but the mod will work.Good luck.
