I guess I spoke to soon in a way. I was going to do the swap (even had a tailhousing from the 300sd tanny off) but was offered a lower mileage tranny in trade for my 300d tranny so i never even bothered pulling the other tailhousing, I suspected there would be loads of gears that would explode in your face as soon as you pull it
