Borg warner? 9 BOLT? yeah got to thirdgen.org or 9bolt.com its better than the 10bolt but nothing like a dana 44 12 bolt, 9" or dana 60

Supers

it is better than the 7.5 10, but there are like 2 gear ratios avail for it and that is it...
i believe 3.9 and 3.4

sorry. i did mean 9 bolt.. just getting wasn't thinking for a minute.. i'll check those sites.

Are those any good though? are they worth it?

Cronic_Moronic

They are stronger than a 10 bolt but there is very little in the way of after market support for them as they are a pretty rare option.

Replacing wheel bearings and pinion bearings should be the same as a 10 bolt though, right?

go check out those sites

the gears idk what the other guy is on but they have many ratios 2.77, 3.08,3.27, 3.45, 3.70 all came stock on the f-body.. and also 4.11 , 3.90 just about the same ranges in gears as a 7.5

good rear end , about as strong as a 8.5 gm set up . gears are plentiful for em , center section is rough to rebuild as the last i tried ya had to replace all or nuttin but that may have changed in the last few yrs . i had one in my 87 formula and it took many low 11 sec passes and 1.5x 60 ft,s

is there any 100% way of confirming this is the rear end, and where would be a good place to look for a diff cover for this?

93v8clone

look for 9 bolts on the cover , if there is 9 ya have the "aussie "rearend . if ya have 10 ya dont .
