Any GM alternator can be used with either bracket kit. Both mount the compressor on the top passenger side, and the alternator on the top driver's side. The 60404 kit can adapt a GM power steering pump, which mounts under the alternator on the lower driver's side. The Ford Engine Bracket Kit is very engine and vehicle specific. Ford engines are very hard to adapt brackets to because of so many different pulleys, pumps and front timing covers.
Engines differ even from year to year.
Our kit uses very specific components and pulleys. It requires a Ford Motorsports reverse rotation water pump, any Ford alternator, a Ford plastic power steering pump, and a Sanden air conditioning compressor. This kit may not fit some vehicles. If you have any questions on the fit to your engine, call the Painless tech lines for help. Relays as Insurance A relay is the cheapest insurance you can get.
