Does anybody know the ratio of the aw71 od and the 5th gear of a m47 tranny. I guess i m just looking for the final last gear (ie) just what the od is and just 5th on the m47

      Thank you, how is the m47 holding up in the turbo? What rpm are you running at 70mph or kph equlivent? and what rear end gears? Thanks in advance. Dave

        Hi Dave

        I Did my M47 conversion over easter. I quickly found out that 2 gear synchro is worn and it jumps out of gear sometimes. But that doesn't over shadow the fact I now have a 5 speed box

        70Mph = around 112kph The car does around 2500RPM at 100kph. I have a 3.54 rear end in my car
