Can you form your statement in the form of a question?
I have the 10* clocked adapter.
The driveshaft will need to be lengthened.
You will need to build a custom crossmember for a flatbelly and you will need either a 2" body lift, or cut out your floor to achieve one.
I'm running a double cardan shaft in the front with the large joint up top. In the rear a regular CV shaft.
I'm not running high pinion because having duals eases your shaft angle anyways.
I don't understand why you would need to cut and turn your knuckles unless your suspension geometry is incorrect.
