NV3500 VSS signal compatible with any aftermarket Speedo? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

What is the value for a speed sensor for an 1990 model NV3500. I have found numerous conflicting numbers on the internet. 40 pulses per revolution, 2000 pulses per mile and 4000 pulses per mile are a few. I can't seem to find out the exact one and if I can use any aftermarket electronic speedometer with it. I will buy the cable x box if I have to but I have to buy a tach also and would like to get them to match if I could plus it would be about the same price. Anyone got any ideas?
