I have a 93 Dakota sport with the 8.25 with a 3.55 sure grip. The diff is the same width as my 74 duster that has a 7.25. I want to swap them out but the Dakota has a 6 bolt pattern. do all the 8.25 use the same axle? can I swap out an older set to get 5 lug? or could I get them redrilled? thanks currently own 1976 duster deluxe 1974 gold duster 1993 Dakota sport 2000 caravan 2002 Durango 1970 v code superbee

The newer rears resemble the 8.25,s but are actually 7.25,s Either that or the newer 8.25,s are built like the older 7.25,s I had what I thought was a newer 8.25 in a 90 Dakota Sport, but when I removed the back cover it was as chincy as the old 7.25 were. I dont recall if I confirmed the cover bolt count, as the 7.25,s have 9 and the 8.25,s had 10. I had just assumed it was the 8.25 by its looks and bigger mass compared to the old 7.25 rears. I was just checking this rear for its gear ratio as it was a parts donor truck, and I was considering keeping the rear. After inspection, off to the scrap it went.

They say there is always the exception that proves the rule. Don't be the exception.

To the OP, like I stated you might not have the 8.25 Had an 87 Diplomat with a 7 1/4, everyone said "10 bolt = 8 1/4" But the housing cover was not 8 1/4. Turned out at some point Chrysler added one more bolt to the 7 1/4 cover (dunno why). http://www.moparts.org/Tech/Archive/axle/6.html They say there are no such thing as a stupid question.
