WTB need 70 challenger driveshaft

[ogre]

Happy New Year!

I am hoping I can find a driveshaft for my Challenger project, closer to home the better.

this is the one i think I need, as my 70 Challenger has an 8 3/4 rear and a 383 4v, 727 AT. The magic length appears to be 45.60" center to center for u-joints. Let me know if anyone has one,and how much.

Thanks for reading this!
