dip stick length

This is exactly what happened to the lady I got the car from, the shop she used must have lost hers and replaced it with a newer cars stick. They used a grinder or something to make the fill marks. They must of knew that there was only one way to put this stick in so that it didn't hit the crank. When I checked the oil for the first time and then started the car up, the crank sheared the end of the stick off where they had used the grinder, must now be at the bootem of the pan because I haven't had any problem.
