All:
Thanks for the help on this. I was able to order what I needed from Moss after some back-and-forth looking at photos, the parts catalog, and the car. I actually got everything together until I goofed up and broke the choke cable. We originally had the choke and accelerator cables hooked up and ready, but had to disassemble them in order to get air filters on correctly (access to the attachment bolts on these air cleaners are hard to reach with the choke in the way). I'm pretty sure that most everything I've installed in the car has been installed at least twice - once to put it on, then a second or third time after relaizing something underneath or behind it needed to be installed first.
Unfortunately I ran out of time and have returned to Washington. More work will have to wait until Columbus Day.
