Honestly I think it has to do with whatever yoke is used when they build the driveshaft. I had the GkTech shifter with the aluminum 1 piece shaft that Mazworx supplies with their CD009/SR bellhousing kit, and the driveshaft yoke did not hit the shifter anywhere. I think there's two different size driveshaft yokes that these shops can use and one has a slightly larger diameter or something.
