You'll need a bushing to fit over the Jeep cam sensor. It's a smaller diameter and I don't believe it has a provision for an O-ring as a regular distributor does.
Also, the reluctor wheel depends on what year LSx computer you get. The earlier versions used a 24x. I think 2006 was the change to 58x. I can make either one to press fit over a factory Magnum crank pulley, if needed.
Furthering the confusion, some of the newer models also used a 4x cam signal instead of the conventional 1x. And some are drive-by-wire while others are drive-by-cable. Plenty of variables to go around.
