Jeepcat,

I'm a bit of a noob, but doing a swap myself. I've been doing a lot of research, and there is LOTS of info here!!! Gauges should be easy in that you should be able to swap your Jeep senders as appropriate. As far as air cleaners, sky seems to be the limit from simple K&N cones on through custom made intake tubes and boxes. Look around for awhile and you'll see.

Good luck!
