General
The LT 230SE transfer box is mounted at the rear of the gearbox and transmits drive via high or low reduction ratios

www.ashcroft-transmissions.co.uk/ has the shift linkage kit. this kit is based on the 03-04 style shifter. this style engages the dif-lock by moving the shifter sideways.

I also have a DI linkage that can be installed onto the transfer case in your truck. There are plenty of instructions on how to do the installation on the web. Before places like Ashcoft developed their kit, it was the only affordable alternative to the '04 linkage. My complete linkage assembly is $150 including shipping. If you have any interest in what I have drop me an email.
