I just changed ours on the old 92 L-10 with a side radiator, The alternator and AC compressor bolts were a bit suborn but some penetrating oil and a breaker bar got everything freed up. The NAPA part numbers were written right on the existing belts so I ordered off of those in advance. We saved the old ones in our tupperware basement bin for any roadside need later.
Total time both belts and checking the alternator bearing was less than an hour
FOR THE WIN!
