Torsion bar lengths???? c body fit b body?

I have a chance to buy new torsion bars that were ordered for a 70 Newport. Now I'm wondering if they are the same length as my 1971 Charger? I figure they might be but a little more heavy duty. So will they work?

Different

Not only are the lengths different the ends of the bar, the hex, is different. The C bar has a larger hex than the B bar.

Ahhhhhhh dang it. I thought I found a deal. Guy had them brand new in the box for $50.00 on craigslist and I figured they would work for my 71 Superbee (trying to pinch penny's to get the car on its feet again).
