Hi Paul: I used the lower set of holes plus have the ride height around an inch taller than specified. Some of the streets in my city are terrible and was concerned for the bottom of the grille.

As a result the driveshaft hit the frame very hard, partially because of the BBC/‘Glide combo. I cut that chunk of frame out and then reinforced with a driveshaft loop to get strength back plus additional safety.

Never thought of a limiting strap...that’s an awesome idea.

Best Regards,
Pat
