73 Challenger 440/727 Driveshaft for 8 3/4 Rear End

Hi everyone, first post here:

Got myself a new project on my hands.
It's a '73 Challenger that one of the previous owners swapped a 440 & 727 into.
My current issue is I have no driveshaft...
Would I be able to get away with using a driveshaft from a 1970-71 Challenger for my application, or would that be all wrong?
I was able to find a Mopar Driveshaft Measurement Chart that states for 70-71 Challengers, their driveshafts had a length of 45.60" and a diameter of 3.25" - does that sound way off?

Theres nowhere for me to get any definite information on this being that 73's never came with a 440/727 package, so I hoping one of y'all have some knowledge that might help me out.

Thanks!

Welcome to the site .
Nothing changed between 70-74 so any Chall with a 727 & 8 3/4 diff has that length driveshaft , the 70 spec will be correct .
