Tk to M5, longer speedo cable?

[4EyedTurd]

Going from a TK trans to a M5od and the speedo cable that runs to the transfer case is way to short now. Looking at Rockauto, they offer a 72" and 80" cable. Which one should I use?

Don't look it up for an 83, look it up for an 88. There should only be one cable that year and it will work for you.

Ok, I tried a 92 and 94

They used to make speedo extension cables, 3" to 20", but with the switch to electric speedos in the mid-1990's they may no longer be around.

When I look it up for a 91 I only get one result.
