I don't recall seeing multiple speedo variants for OD vs Non-OD trannies
although the unit may have changed/evolved over the years. Adding an
unaltered Volvo J-Type or using the wrong speedo drive pinion in any OD
unit will definitely cause incorrect speedo readings however.

The speedo was reading on the - 20, so at 55, i was really doing around
75.
Of course being a used one, there could have been something wrong with
it.
I am not sure how u visually tell a difference; but the used one that i
got
is marked 206-20; on the inside. My original had a different set of
numbers
marked on it.
