The 2.3 in my 81 Courier doesn't have enough compression to run properly, the trans is a little clunky, and the front end is worn out.
Fortunately, I just parted out a Wagoneer so i have a pair of D44s, I also parted a Mercedes diesel so I have a 5-cyl turbodiesel engine (OM617 for those in the know), and I picked up a M5R2 transmission. Stay tuned for details-
