Seems like these kits continue to evolve (version 4?) and have small issues that still pop up (based on posts in this thread). I may wait for version 6 or so
Only difference between version 3 and 4 was a latching sensor to make sure the hood loop is seated in the latch before pulling down. There were also inconsistencies in the manufacturing on Tesla's part. My two MYs are identical build and less than 50 apart for VIN and the lower threaded mounting points were off from each other about an inch from car to car.
