ED,The Camaro pad I think you are speaking of goes on the top. While it would allow triming off coils the Camaro springs were a fair bit smaller in diameter so you would be could not use a "B" coil.
TWOARES, While you might be "happnen" today , think about what your first coil is up to. Non pig tail springs that are used in flat pockets are typically ground flat or at least have the first coil pre flattened. You with your cut open coil end will likly have the first coil crammed down so the second is right on the cut end. Or you will find the first coil swaying sidways to miss the second. Personally I do not think your method is the best procedure but if it works for you today, fine. I would not how ever advice others to do it as there is a very real possibility of your first coil breaking in time from being nicked by the free end or over loaded. I have not even bothered talking about the location deal as that is a given. Good luck. Gerry
