Outer Limits 4x4 Board

Hi all

I have a snake racing Hi Steek kit installed on my sj40. What I would like to know is can I use this kit onto a WT 91 model.
I know the drag link and tie rod might be different, but the actual Steering Knuckel?

Thanks again

Knuckle is the same on all sierras except the coiler.

Steve.
