Hey this is small!!!
The Tribute is big

I think it would be safe to drive your car with the hardtop on for 2 min, even without the spinlocks. Just drive really slow... It would fly as it was said if you were going to drive on a highway or something...
Since the bodyshop is so close to your house you can always take a friend and carry it. It's not heavy anyway...
Anyhow, it is safe to leave the top on the car without the spinlocks. It just sits in the holes (where the spinlocks go)
