This same question was asked a couple of weeks ago and I believe someone replied that Bender used to or perhaps still sells a timing key.You might try Hauck too.
I have never seen a flywheel offset key that will give a 7 degree offset. I don't think there would be enough thickness in the key to allow it.
If you want to advance that much you may have to look at other options like installing a 2002 Viper CDI.
