I am wondering if you gentlemen are leaning on swapping the differential, or have Quafe build one out of your own diff? The difference is swapping takes almost no time, if they have the parts they will just swap it in, but it would be someone else's diff to begin with. However if you want them to build it out of your very own diff, you will have to endure some time without the use of your car, as the LSD is built out of your car. Just wondering.
