Last night I fitted the refurbished driveshaft and tested it without having any issues at all, it took about three hours to fit the new joint and install the shaft back in the Jeep.
As the photos show the boot on the transfer case end has ripped, probably around the time of my last trip to double island point due the joint being full of what feels like sand.
And the new joint
The replacement cv joint i got off ebay for $110 from Drive Shaft Parts in the US, the part was $80 and arrived a week after ordering. The part number is ME807 and the kit comes with bolts, circlip, grease and the joint. However due to the size of the aftermarket bolt heads compared to the OEM ones, it is a good idea to keep hold of the originals. Here's the link to their ebay store:

If anybody else is to do this make sure you mark on each end of the shaft and the companion flanges a bolt hole to use as a reference point so the shaft goes in the exact same way it came out. Also as cmohr suggested loosen the exhaust bolts as it makes it a lot easier to remove/replace the shaft once the companion flanges have been unbolted. When replacing the joint only remove the cover at the end that butts up against the companion flange as the circlip that holds the joint on is under that cover after removing it, it should slide off easily.
This write up is really helpful for this issue as well:
