Anyone using Calvert mono springs on their car?

I had a set on my old Dart and liked them. Was wondering if anyone has used them on our B bodies? Mine is a 73 Roadrunner. Not concerned about it being non stock, just with regards to fitment and driving quality.

Yes, I use them on my 63 Fury street car along with a set of Competition Engineering bars. Ride is a little stiffer than stock, but not bad. Front spring eye bushing is aluminum and can 'growl' if not lubed well.
