Iv got 3 1/2 impacts including the ir like you posted and Iv had issues before. Its mainly with cars that have never been apart.
If you get the big impact (1") be careful it can and will snap crank pulley bolts as well as snap off the end of an axle if you use it at full power. Shops that do semi repair usually have them. I used to do semi repair and that is when I got mine.
