The ones off of a Waggy V-8 will work, but you should get all of the accessory brackets (p/s too) and pullys. Use them as a set so that everything alines and the belts will be a stock application. Get the attaching bolts, too, some are long or odd stuff. A/C won't matter on most I've seen, a separate belt went from the alt to the a/c compressor.
