Idle Stabilizer Control Unit for DJ Engine- Rebuilt

This is the idle stabilizer control unit that is for the DJ engine ONLY!  It looks like similar to the unit for the stock 2.1l Vanagon, and the part number is similar, but it is not the same.  The price is $225 plus a $200 core charge.  I only have one of these so I really need your old one back.  Don't buy it if you don't want to exchange the core.
