I take it you want to keep the 3.9? You would put the 3.9 into legacy trans since that's the 1 going into car?

Was there a reason you wanted to do this much extra work? Gas mileage?

The legacy trans is going into the svx because the trans on my svx is shot

Ok so the 98 legacy trans is going into the svx but the problem is the rear differential has a diffrent ratio so I need to change the ratio of the rear differential

Why is it a problem? Ratio does not seem that far apart? Do axles fit in the 444?
