you are looking for an obd1 vr6 water pump pulley, then you can use the serp belt on it instead of the v belt.
It looks to me like he has an AAZ water pump pulley from the AAZ A/C serpentine setup on his water pump.
I got a hold of the pulley and new Idler. This belt is a 1045mm. It look like it's a little bit long. I am thinking a 1035mm or so would be better.Since this is the first time I've seen this setup. Is this correct as far as the belt wrap?Thanks for the help in finding the parts.Tony
