After a good bit of part number cross referencing, I find that there are two front axles listed for 94-03 B-series vans, a 3.3k and a 4k. The 3.3k axle has both 5-lug and 8-lug options, and most importantly, both ride on the same spindle/knuckle (OE p/n Left-52058415 & Right-52058414) AND use the same brake caliper mount (OE p/n 3699992). Since my '94 B250 is listed as having the 3.3k front axles, I'll be running on the assumption that 3.3k 8-lug rotors can slide onto the Dakota drop spindles. I'll report back if any fitment issues arise.
