griffbl,
You might to try the AC Owners Club forum,
The AC Owners Club website home page.
There's plenty of help there as well as a few knowledgeable guys here.
Some of those items are Land Rover parts bin stock.
I had one, and there's a few surprises in them. How heavy is your hood? IIRC, the hood was backed with another layer, obviously for strength. There's also quite a bit of bondo making those bodies look stunning, which it did. I didn't recall the louvers but it doesn't surprise me one bit. It was an awesome car and I would have kept it if I could have put a BB in it.
