that little annoying thing is still hanging there. Not sure what it was. Had a little plastic clip going through the hole, maybe it held some wires. Strange thing is, my bro's 96 explorer intake doesn't have it. I told the alum polisher place to hack it off even, but they thought it would look funny if I did. I still think it would have looked better flush, but that's alright, I can take care of it in the future.
Update. Everything is 100% together, and I tried cranking it up. I've got a big problem somewhere, and I'm nearly certain it's a starter. It cranked a couple of times, then nothing but a big CLICK and smoking batt cables. Too much resistance. Turn the engine manually with a socket, get a scraping sound, then that frees, and spins nicely as many times as I need it to. Only get that noise when I've engaged the starter, so....I think I'm a starter away. Will update fri.
