Update: The nice lady at Classic Parts contacted me today... She said their main boss and their own technical guy both agree the CPP sent wrong parts, and no way it would work.
They are taking care of me. As far as CPP goes, she said not to expect any communication from them.

Classic Parts = Good Folks...Rock on!

CPP = Boooooooo.
