Just to provide closure on this, first of all, thanks again for all the advice. I did call Randy's but they did't have the gear-sets. Although I have come to find that the 1/2 ton Napco gear sets are the same as the 2wd versions. On the Napco set-up the front & rear differentials ratios need to match. I called Patrick's & he said that you can find the existing ration by the two numbers etched into the back of the pinion gear. However, he only carries 3.38 gear sets, I know my existing gearsets are not 3.38. Therefore I am going to bite the bullet and get two 3.38 gearsets from Patricks. I have a lot invested in rebuilding the front & rear differentials and the transfer case already. Also I picked up another newer 3 speed overdrive. So from a long term perspective it should be a reliable set-uop and a good highway cruiser. Again tthanks for the feedback and pointing me in the right direction.
