P/s Pully Troubles 70 340 Dart

I've seen some aftermarket bracket kits that looked nice. Some use serpentine belts and billet aluminum pulleys while others use stock pulleys and belts.
I pretty sure either type will require the later aluminum water pump.
I'd like to see a pic of the pulley you need. A friend near me has a huge tote box full of variuos pulleys and I have atleast 2 p/s pulleys here.
