Almost 700, I reread your post. If your track is off the ground in the back, your control rods are too short. There was a thread a while back about this. When I first did my sled I didn't have the drop brackets, and the rear of my track sat about 3'4 of an inch in the air. You can add a spacer to the bottom of the control rod to lengthen them and allow the track to sit flat. If you can't find that thread, I can look for my old spacers and give you the measurements. They helped until I got the brackets installed. Let me know.
