I'm building my 67 Chevelle and it still has the original 12 bolt posi w/4.11 gears. I have to go down in gears to a 3.08 due to I'm building a turbo LS1 motor and buiding boost for any reasonable use w/4.11's is not an option.
I will need a new posi unit for sure since I'm want to upgrade to 35 spline axles. Any recommendations for a good street use posi that will accept either a 2.73 or 3.08 gear?
