The parking brake release handle, if normal under the dash style and not next to the console, comes from the old European "Capri" vintage early 60's. I don't have a picture on this computer, but they can have either a chrome or I believe black handle, with a white plastic release lever.
I have seen them parting these old Capri's out, best to search UK-eBay and related car sites!
The rest of the parts are pretty much hand made from strap steel. We can help you get dimensions etc I'm sure!
Had a gas in Houston at the show!!! Glad to get out before the REAL weather hit!!!
