I just got a 5 speed NV3500 transmission and a stock transfer case that came with it. My problem is that it has an electronic speedometer port and my 1986 chevy 2500 has a cable type speedometer. So what do i do for a speedometer?

 

take it to a speedometer shop. speedos are their own little world and they make special adtepr that go from electric to gear driven and whatnot
