Peter, I may have one, will have to go searching in the used parts room, then it's a big expensive shipping to you from here.  However, if it's running and making a lot of noise perhaps and most likely, the fan is running on high speed instead of low speed.  A very common ailment on the vans with AC as yours.  The ballast resistor that controls the low and high speeds of that fan are behind the left front headlight and they do go bad VERY often allowing the fan to run on only high speed which is VERY noisy.  Have your mechanic check that circuit and make sure the fan is working on both low and high speed.  Ballast resistor and or the thermo switch in the rad could be at fault.
