A freind of mine just got an 84' sub silverado he plans on parting out. It's 2wd 2500 series with 8 lugs 6.2/th400 and tow package. I have yet to see it and he's not too up on describing things over the phone. What are the chances it has a 14b out back? I'm thinking it does. Also, what type of gears would you guess were in it, assuming it's facotry?
