I'm not aware of any 5-speeds that were mated to 3800s from the factory so then flywheels, custom adapter plates, custom cv axles, custom pedals and linkages, custom tranny mounts, not to mention potential computer interface problems might all be happy things to fab up.
However if someone knows something about this swap and it turns out it is an easily/cheaply doable thing, I'm all ears cuz I'd have a splendid app for that myself!!!
