first of all removing the rear drive shaft is a bad idea, ever heard of a slip yoke(think draining all the transfer case fluid out, say bye bye to tc) unless you feel like installing an sye kit.

hub locks might work.

i'd try a grill block, remove wipers(unless needed), change mirrors, hard top(not soft top; cd changes between the two), gas cap door maybe, remove the side steps, cover in the plastic fender wells; the expensive part is underneath belly up skid might help, custom gas tank it hangs way too low, someway to smooth the airflow from the front to the skid then back from the skid to the gas tank, section/drop the back of the hard top(maybe)

and too the people guessing on the d30 it's in 200-250lbs range fully dressed, the driveshaft is about 20lbs probably more knowing chrysler and the transfer case is around 75lbs dry
