Oh, FANTASTIC! I love that big one piece SM-465 & NVG-241 shift bezel. Really really glad to hear that the OBD-I ECM was able to deal with your changes and that it runs great.

Dang! I think I know where most of the red interior parts are that you're looking for. I'll shoot off some emails and see what I can find. Do you want the correct early bench (pre '95 interior) with the single fold down armrest for the driver? Love your to-do list, really great upgrades you have planned. I installed the medium duty door handles on mine a month or so ago and I love them, just flat love them. Mine have been sand blasted and powder coated gloss black as well, I'm looking forward to what you may do with yours. I always thought body colored buckets and black handles would look good.

EDIT: I also know where a full set of cab lights are, harness, fasteners, etc. I do not know lens/gasket condition, would have to look. I recently put the factory LED clearance light bulbs in mine and they are awesssome. However, I am having water problems now, prior to bulb upgrade everything was dry, now I'm getting a wet floor and a couple lenses are partially filling.

EDIT #2: Forgive me if you've crossed this bridge already or already have it in your notes...when you put the PY0s on, if you want to run the -400 center caps you will need to use the black nut covers from the -800 caps to hold them on, there may be another solution, or a better one, but that was my solution for the problem when I encountered it. I observed that the -400 cap sits further out on the PY0s, just far enough to prevent the nut covers from reaching the lug nuts. If you (already have) solve this differently or observe something else, I am looking forward to your solution.
