One thing worth mentioning about the Tru-Ram manifolds is that you’ll need to figure out what brackets will work on your particular application. I opted to contact Alan Grove Components (AGC) to get the brackets for the alternator, A/C compressor (which I’ll be installing at a later date), and the power steering pump. That said, I had AGC send out a matching set of pulleys as well so there’s no guessing game when it comes to putting together a set. The crank pulley is a triple groove while the water pump pulley is a double groove. Also pictured is the single groove pulley for the power steering pump.
