Front axle is gonna take alot of work, since it's a leaf spring axle. I also believe the clocking of the transfer case is different and make cause interference with the MJ body.
Besides keeping the fleet of Jeep's running between my house and my parents home I don't get into much. Helping raise my 6 month old boy, keeping the house together and just chillaxing when I get the chance.
I'm a big fan of the Thrush Welded mufflers. Depending on your area, replacing the Catalytic Convertor with an 18" glasspack compliments the muffler great! A distinctive sound and just enough volume.
