What Kenneth said.
I put 3.42:1 in my posi 8.5 and I'm wondering if I shouldn't have gone with 3.08 or 3.23 instead.
Don't forget that if you do decide to change your gear ratio, you will also need to change your drive and driven gear at the transmission end. Both are easy to change, although the drive gear is a little on the messy side since you need to remove the prop shaft and tailshaft to access it.

posi unit
Yes that will fit fine... It is a 8.5...The pinion shaft is the dead giveaway.
Go grab it looks like an original Eaton Positraction unit. you can rebuild it too even if the clutches are worn out. Jim
