Those who flipped a dana 300 with a mechanical cable from the transfercase to the speedometer, were you able to use the stock cable or did you have to get a longer one?

Mine is not exactly as you ask. It is electrical.
But mine would not be longer, it would be shorter. Where the speedo gear for the np231 was it further from the dash than that of the d300.

Don't know if this helps at all.
