On my scale of 1-10
7.5" 10 bolt 5
7.75" 9 bolt 6
8.5" 10 bolt 8
8.5" Dana 44 8
8.75" 12 bolt 9
9" Ford 10
The 9 bolt is stronger then the 7.5 10 bolt. If you can get one for little or no money it's a good upgrade, If you have to dump a lot of money into one ( ring and pinion and posi ) then just jump to a 12 bolt.
