Do not forget the added cost of adjustable upper control arms because you will need to point the pinion upward straight at the transfer case output.
A SYE is not hard to install, hell I do dozens a year, almost anybody can do it with the correct tools. Get a good pair of lockring pliers, the ends look like duckbills and are knurled.
Having a TJ or XJ front driveshaft shortened locally is a good option, runs about $65 here to have it shortened and balanced. Once the pinion is pointed up at the output yoke, measure center of ujoint to center of ujoint on the two yokes.
