I have two transfer cases. One has the mounting boss for a speedo and the other is blank. I'll be using the correct tail shaft housing to make sure I have the speedo output. If the output shafts are different between the two, then I'll have to swap that too when I rebuild the sucker.

It's good to know that my speedo cable will fit; that means less stuff I'll have to fabricate.

Thanks to the both of you,

Aaron
