Maybe it would be cheaper for an atlas 4spd... A little heavier duty unit, I used a shop discound I think it cost me around 3k for my four speed. Not sure how that compares to duals from scratch but it seems like it would be comparable.
Duals aren't really that pricey.
$370 for Marlin dual case adapter
$100 for second transfer case
There ya have it. Factor in other things such as new crossmbmer / way to mount it all, and you're still easily under $1K
For Collier, he'll have to get a new tranny anyways, so why not go with a W56 or a R151? Then you get a gear-driven t-case with the package. AND he has a line on them CHEEAAAAPP!!! Ahaha!
