Things like this are one of the reasons I bought a cheap Chinese mini-lathe. I don't need to turn an axle housing these days, but whipping up something like this is a great project, especially when you have a pattern to go by.
Thanks for the tip. I called Chris Robbins, and he didn't have the part; but he told me to call Tim Halter, who is the Ford convertible top guru. I called Tim and he didn't have the part either.
