I assume "d" is referring to Diesel. They come with a welded ring gear and a ratio that is very different than gasoline powered cars. To install a Quaife you are looking at $1000-1200 in machine work plus the unit. It's really no different process wise than the gasoline cars with welded ring gears other than the ratio is different.
