The Arizona Dart - teething.

Very clever. For the future, check ebay once in a while. You see used carburetors all the time for ~$15 that would be good for parts. Might be hard finding a Carter BBS w/ a throttle rod, since that ended in 1964, but later cable-thottle types might have most of the same parts. I got a new Carter BBD for my 65 Dart (273 engine) for $25 a few years ago.
