Doesn't really matter at this point what year it is. a stock truck (of that year) will have about a 37:1 crawl ratio.
here is the breakdown of gearing assuming you have stock Ring and pinion gears
Stock single case: 37:1
Single case w/4.7: 76:1
Dual stock cases: 84:1
Duals w/4.7 in one case: 173:1
Duals w/4.7 in both cases: 356:1
so, you need to decide what type of driving you want to do with your truck, and change the gearing appropriately. in most instances dual cases with 4.7 gears in one case will be enough to get you by, but some of us like to get extreme ![Thumbs Up :thumbs:](https://board.marlincrawler.com/Smileys/marlin/thumbs.gif)
That's cool, that info is useful. However I'm kinda looking to see what the specific gear selection options were when using dual cases. Specifically, if I were to use the 4.7 gears in the front case and vice versa.
