Of course, it has a 9" tire and not much room for any larger [I do not want to cut the car except for minor trimming if needed.]

Help me with a good setup for this situation. It will weigh around 3050 - 3100 with driver.

Adjustable upper control arms, HR Parts N Stuff antiroll bar. Does the 12 bolt in the car have the raised mounting points on the housing like the newer Moser housings? If not, you'll need a set of no-hop bars to correct the instant center. With all of these things it will work perfectly fine with a 9" tire.

There is plenty to be had getting the front end to work very freely as well.
