It's length makes it a good fit to replace your stock trans without having to modify driveline lengths. A good way to help offset the cost of these little goodies. These conversions are not for the faint of wallet.

Yes there is a new output shaft that will adapt the 4l60e trans to the 203 case.
The adapter between the 305 and 203 transfer case is the same for the 4l60e.
Here is the correct part number you need.
ADV 50-6900 the kit runs 162.99

I have a 4L60 auto trans with a 4/wheel drive rear shaft, will this shaft be ok to use to adapt your 4L60 to my 1997 NP231 transfer case. Also, if my shaft will work can I buy your adapter minus the out put shaft and then what will the adapter kit cost.

What year is the 4L60 transmission? There are a few different kits that don't require a new shaft depending on the year.

Both of these transfer cases would need an adapter kit to be mounted. The kits are different depending if it is a 4wd turbo 350 or 2wd. Then there are different input splines on the 231 and two different Dana 300's.
Advance Adapters got its start in Downey, California in 1971 with a single adapter mating a Muncie car 4-speed to a Jeep Dana 18 transfer case. Eventually headers, overdrives, motor mounts and linkage brackets were added to the offerings to complement their core adapter components. When interest in rock crawling spiked in the mid-1990s, Advance Adapters offered low ratio transmission swaps then switched gears into the ultra-low gear transfer case arena. Today, the company is based in Paso Robles, California and their engine and transmission conversions for Jeeps are in kit form and sold as individual components. Shop Advance Adapters Now
