I would be willing to bet youcould build your own for that kind of money.
I personally wouldn't want the OP loss and road hazard exposure to another
30' of oil lines!  I took an evaporator coil from a 1975 monte
Carlo(harrison product) and had 1/2"  female aluminum pipethread fittings
on the orifices and mounted it in the rear air flow of the vehicle with a
separate air scoop and ducting for the hot air out the rear.  Using a
simple adapter plate(some even come w/ built in thermostats), I had  the
right length stainless steel teflon hoses made(#8's) and you now have a
cool engine.  This was done to my Type IV, but could easily be adapted to
the WB.

> Hello folks,
>         I saw an ad in a German magazine (VW Scene) for an add-on oil
cooler system that put a unit between the block and the oil filter which
pumped the oil to a small radiator  mounted underneath up front by the
spare tire.  In addition to cooling the oil this system would increase oil
capacity, a definite plus, I should think.  The price was about 150dm.
Does anyone know where something like this might be available in the US?
