The Jeep in question is a 1985 XJ equipped with the 2.8 V6 and 907TF auto. I'm replacing the NP207 and I'm wondering if the output yoke that attatches to the front driveshaft could be converted to a cardon-style piece from the NP231 easily. Would it be more worth it just keeping it the way it is? It just doesn't look promising with the grease being protected by only the boot. Also... does anybody know how to put new caps on the Ujoint connecting the front ds to the D30? The caps are missing and so are the bearings and whatever else is in there. Thanks guys! -Mike
