Alas, we are not psychics.
Your post does not tell us exactly (or even generally) what Suzuki vehicle that you have.
Your post only tells us of your goal in very broad terms - you want to crawl using "about" 6.8-1 gears.
The first thing you need to do is read and learn more about whatever Suzuki 4x4 truck that you own, then start asking questions here to fill in the gaps.
Knowledge is the best tool to use to reach your goal.
I would suggest visiting Ack's FAQ (
http://www.acksafaq.com). There is an easily-searchable database of over 800 links to helpful information on the internet - much of it found right here at Zukikrawlers.com!
Ack's FAQ also has two useful gearing calculators (one designed specifically for the Samurai) that can help you create the gearing/tire setup most suited for your vehicle.
I hope that this helps!
