I've got the '83 non-waste gated, non-EGR, non-IC setup (TC05 turbo). Using the spacer on the exhaust side moved the entire turbo out. The compressor outlet points straight up, without any room for misalignment from the 90* elbow that bolts to the intake mani. Further-more, on the non-EGR intake mani, that elbow is at a 45* to the long axis of the engine. The easiest place for me to fix the gap was between the intake manifold and the head. I'll take a couple photos when I get home from work to show what I did/what I mean.

Like I said before, the easiest solution is to simply drill and tap the exhaust manifold. When I made the spacers, I still thought the diesels were rare enough that I'd likely never find another manifold, and if I ever wanted it to be 100% stock again, permanently modifying the manifold was something I wanted to avoid. I've since picked up another 2 diesels, and another 3 manifolds, and knowing what I know now, I probably would have just taken the easy way out.
