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
So it looks like Chrysler used the notch bars in the Dart conv?? If I'm following correctly the Dart conv. rod is 42". If so I'll take them.
