67 dart convertible trunk torsion spring length?

Cuda Notch bars are 42 inches.
Dart Hardtop are 44
Ive got a set of the 42's I can do for $40 plus shipping, if anyone is interested
Looks like I missed first dibs on these but I'm in need of a set for my 67 Dart Convertible. I still have the originals so I'm going to go measure them too.
