I got this switch:
C1TF-7A247-A
1960-1966 Ford truck with Auto
I have not installed it yet, but it looks identical to the original switch and is supposed to allow start in both Neutral & Park. I got it off Ebay, but in thinking about it later, I bet a local NAPA dealer could get one for you. I paid about $35.00 for it.
Hope this helps.

BTW, Paul, thanks for the great carb
