I have been looking for a new nose for my 70 firebird and found this on ebay:

I think it's a 73 from the bolt hole pattern. He does not have any pics from the inside. The BIN price is high, but the starting price is pretty good for a re-done nose like this. I have no idea what the reserve is on it.
If you think it is a 70-72 nose let me know.
Thanks
