according to isuzu usa they sold their rights to all their parts to general motors around 2007 - any parts that are left over isuzu can sell but once they are out thats it they cannot legally make any more - whats worse is that many of the unique parts for our vehicle will not be reproduced at all because there was no money in them for gm to do so - in other words once they are gone, they are gone... unless an aftermarket company steps in
