I was able to get the rear manifold at a local junk yard from a van with 166K miles. The removal of the rear manifold takes about two hours. It is necessary to remove all of the heat shields of the front manifold to remove the front union nuts. The rear nuts can be removed after removing the heat shield from underneath the van. This take some time. I was lucky the power steering pump was already removed from the junked van. One advice is to only use six (6) point deep sockets for all those nuts and use the longest breaker bar you can get it fit in the small space. After removing the nuts, you have to remove the studs using a E-Torkx socket. The studs are easy to remove. From the top, it is necessary to remove the EGR, air filter box, and battery base to get the necessary space to take the manifold out.
