Kind of going to be trial and error, but with only 2" you'll probably be ok with stock control arms. You may need longer shocks, but I've never looked at lifting a coil spring 2wd to know. A 2" drop is usually within travel range of a stock shock, so a 2" lift might be also, but it could be closed to maxed out on extension. IIRC the shocks on the coil spring 2wd are in the center of the coil springs, so might want to do some reading on that before digging in.
Even if stock control arms do work, you will likely need camber adjuster bolts in the upper arms to bring it back into alignment. Since you'll need an alignment anyway, I'd go ahead and install the adjusters while installing the springs. Be a good time to check over all the ball joints, bushings, and tie rod ends.
