I'm in the same situation.. I have access to nice 6-lug differentials with 3.73 gears, but all my vans are 5-lug. I have NO desire to switch to 6-lug (requiring new wheels & tires) or run mixed configurations..
What would be nice would be if I could switch the rear, then swap back in the 5-lug axles into the 6 lug differential. Problem would be simply solved.
