new to the forum but not mighty max or ram 50 trucks

I have had a mighty max as my daily driver for about 7 years and love these trucks. My project for this summer is a 89 ram 50 4X4 thats pretty rusted out.

Im for ontario, I am sure ill be a regular on the forum this summer.

Any one swap a 4G63T into a 4x4, is it possible, is it just as easy as it is with a 2x4.
