Just bought my first mopar. Looking for help!

Look into the ford explorer 8.8 rear mod in the drivetrain section. Probably the best bang for the buck IMHO. And upgrades to big bolt pattern, same as mopar big bolt pattern.
I found a narrowed Dana 60 with 4:56 gears winter posi. Stranger 41 spline gun drilled axles. With chevy pattern I believe.
