Per my previous post regarding the sight glass, looks like you’ve narrowed it down to a’67. Thermostatic choke is another clue.
I may actually have one of those carbs on the shop floor.
The DW35 was probably a factory install for SOME Toyota, just not a Landcruiser. That particular sight glass shape was used on Landcruiser carbs from 1967-1969. So you should do an Internet search for other Toyota vehicles of that vintage if you want to track down a kit for that carb.
