Hello all , I recently purchased my 86 k20 and the speedometer isn’t working due to having a newer t-case in it which is coded as a 214c the truck has a 350 with a th400 in it. So my question is can I swap out the output shaft cone on the transfer case I have with one from a np205 or 208 transfer case or do I have to swap them entire transfer case out to achieve my goal? If I do have to swap the transfer case out which one will I need I’m not sure what the spline count is without taking the t-case out and would prefer not to cuz the truck is my daily driver right now.
