On all my 1971 E Bodies I find the 1970 undercoating to be a little different in the front wheel wells. When it comes to my 1971 Challenger it is nothing near to the 1970 year. My Challenger was ordered with very little to none in spots on the car. The wheel wells do not look anything near to ECS version.There is very little in the wheel wells and none on other parts of the car that normally would get some. Dave it is up to you how much you put on. I bet it would be up to the line worker just how much he put on also that given day.
