Andy,
Didn't the Mk 4 have a 4.10:1 diff to compensate for the rotten hp specs
after the emissions changes? The 1500 definately had the 3.89 in the US,
but the mk4 had the 4.10 in the US. I bought up TRF's stock of these years
ago and use them in the race car. definately 4.10, but the later style that
fits the better designed 1500 diff!
