I would think the ride tech would hold that power. They do rec that people that will be running slick bolt and also weld the cradle in place. Also they want you to stitch weld them in a 1in at a time if using stock frame rails becaise they are thin.

I have had great customer service with ride tech so I would give them a call and ask the tech people.

BTW I have the ride tech 4-link in my 79 camaro with their coil overs and just purchased the tru turn for my nova. they make great products
