I just completed a 4.3 swap in a 84 XJ useing a 700R & 231C HD transfer case from a 89 GMC Jimmy. I am trying to figure out how to make my cable speedo work. The T/C looks to have a screw in elect. speedo adapter. Dose anyone have a sugjestion??
Catsass...

 

Take that one out, see if you can replace it with the mechanical one from a 231j...I think its 94 and down.

 

Thanks for the reply. You mean change the transfer case to a J or the speedo assy.?

 

The speedo. I don't know for sure...hopefully someone else will chime in.
