The transfer case drop is mainly to help the rear, but in doing so, it worsens the front angle. If you have adjustable rears, you should be able to dial in the rear without the drop kit. The long wheelbase of the WJ helps you here. At 6.5", I'd get a SYE kit anyways, which completely eliminates the drop kit. But that's me.
Carolina is certainly an option, and has been discussed much lately.
There are other options, however.
You can source a factory dana/spicer double cardan shaft from a local junkyard or Car-Part.com--Used Auto Parts Market
. Get any yokes that you need and you're set. This is a cheaper option (and better overall quality in my opinion), but you may need to slap some new joints in there, which will add a bit to the cost.
Depending on your axle placement and size tires, you may be close to maxing out the stock length shaft stub splines. You can cheaply get a stock double cardan retubed to any length, or of course, go the aftermarket route.
By any chance, did you pick that WJ up in PA? I think I saw it listed somewhat locally. Make the seller reimburse you. Pretty shatty for the front shaft to fail on the way home after the sale.
