Hi Joe. I have Detroit Speed uppers and lowers in the car. They do not have a provision to clamp the brake hose, but when I built the car I ran the suspension on both sides through full travel and checked the steering lock to lock at the same time. I’m confident the hoses will not be caught anywhere during suspension travel or when turning.
As far as the steering stops are concerned, I have them, so I can’t comment. Plenty of aftermarket an arms do not have steering stops. My blue Nova didn’t have stops (TRZ a arms). The guy who bought it is still delighted with the entire car, so you can take it from there
.
Good luck with the build and if you have any questions, fire away. I’ll answer if I can.
