I have a few of these laying around but pretty sure the only 9s211 I have is currently in the blackberry.
You should be able to use 9S210, 9S211, or EK805. I couldnt find any difference between 210 and 211 other than production date. The EK is for the 2004 model year which should be the same. The hard part here is the VDC. Not many trucks were equipped with this and the computers use a different protocol to communicate. You could probably get this back on the road using the incorrect computer but you may get VDC lights or engine lights.
