I so wish the XK had been designed with a solid axle front and rear. I just know from little experiance helping out with drag cars, adding rack and pinion and putting 9" ford rears in Chevy muscle cars. It takes quite a bit of fab work. It has to be RIGHT. Imagine the trouble getting the housing mounts in the correct spot, aligning with the rest of the drivetrain properly. What is there up in front to even weld to ? Not to mention when the computer freakin shuts down when you start it up. LOL !!
