drive shaft help

[vintagesalvage]

I purchased a 70 charger r/t in boxes only piece missing is the drive shaft, my friends junkyard has 2 barrels of drive shafts but I don't know the size without putting some of it back together which I would prefer not to do until its ready to do so.Does any one know what size I need to look for its a 440 with a 727 and an 8 3/4 rear ?

My service manual says 52.07 inches.  That's Centerline of front yoke bearing bore to Centerline of rear bearing bore.
