He is, mysteriously, quiet....not like him.

As for recommendations of who to contact, I have been working with Rambo, on Team Chevelle for over a week about this issue. No known sources of the correct spring as of now.
If anyone else has an upholsterer/supplier that has a source, I'm all ears.
I talked with NPD this morning and they are having UPS pick up the incorrect springs I got yesterday on Monday for a full refund...I hope...time will tell.
