66 Dart driveshaft length

[xxxhemi]

can anybody tell me the driveshaft length on a small block 904 71/4 rear 66 dart. the chart I've seen says 56.61 but i'm not sure if thats right.Changed over my 65 to a slip yoke 904 and hoping this will be the last piece of the puzzle.

Thanks

My interchange says 56 5/8" so your measurement sounds about right as long as it's not a S.W.
