All '67-'69 GMC V-6's in pickups came with a 2 groove pulley on the crank hub (these engines do not use a harmonic balancer). The first groove closest to the engine is for the alternator and water pump, the second groove is for the power steering pump and water pump, if equipped. There is a second single groove pulley bolted on the front for the A/C compressor. This pulley is smaller in diameter than the 2 groove pulley. Back to the motor mounts, I have been told there is a particular transmission mount that will work as a replacement. I don't have a part number for it, but you might try asking on the '60-'66 GMC V-6 website forum. I believe that is where I heard about it. Hope this helps you guys out. Bob.
