$2500 would actually be a low end estimate. Assuming $500 for tranny and x-fer and front axle, which isn't a bad deal if all those parts are in good shape, then you have approximately $1500 just for a solid axle conversion kit (I haven't priced them lately) which should include the brackets, hi-steer. I'm not sure if the 2WD steering box can be used, so he may need a 4WD box. Then he'll driveshafts. Stock ones could possibly be picked up for a few hundred at a wrecking yard. At least twice that for new ones. Then he'll need a rear axle and diff, which will be a least $200-500 at a wrecking yard. And rear springs, shackles, U-bolts, etc.

And none of that addresses gears, lockers, and cost of labor. If done right, the cost could be kept to nearly the same as buying an entire other stock 4WD truck in good shape. But it would be tough. However, in the end, he'd have basically a '91 extra-cab truck with an '85 suspension and nearly an '85 frame, which counts for a lot if one wants to keep the suspension height as close to stock as possible. It would be a better truck than the typical SAS and with more room, better engine, than an '85 or earlier truck.

As for swapping 4WD IFS over to a 2WD truck, if that's what was meant, it's not possible. Or at least not feasible.
