OK, this afternoon I swapped the original speedometer out for another unit I had. Took a drive about 20 miles to pick up my daughter. Using a GPS speedometer app on my phone, I got the exact same result, the speedometer reads exactly 20% slow. So, that seems to rule out the speedometer as the culprit. Last piece in the puzzle I have not checked is the gear inside the transfer case that drives the speedometer pinion. I have one that would be correct, hopefully when I pull the existing one out it does NOT match the other one I have.
