With the rubicon CV driveshaft kit from Tom woods is there any adjustability to it at all. In other words if I install a 3 in lift now and get the new driveshaft then go to a 5 inch long arm am I going to have to buy another shaft. I have seen some CV's in catalogues that seem to have like a slip fitting to adjust them to different lengths but I would guess that these are less durable. Everyone out there running the TW DS let me know how it works, please. Most appreciated!
