Well, just trying to narrow down your options. It is definitely older than 98. Was it in 98 that they revised the intake manifold or 99? Also, I seem to remember that in some year (maybe 95 or 96) that the exhaust headers or manifold was revised. I can only remember bits and pieces. I'll try to find that thread.

hmmm...it looks more like a 93+ design, due to the difference in the EGR design from the 90-92.
