I think you are talking about the thermal opener on the manifold. Looks kind
of like a clock spring? try LMCtruck.com You may also convert it to a
manual/cable choke for now until you find your parts if you need to use the
beast. A more reliable option is converting to a carb with electric choke.
Personally I'd go with a electric choke. You should be able to find a intake
and newer carb at a bone yard for about50/70 dollars. Throw another 30 bucks
into a rebuild kit for your newer carb and you have 100 bucks into a problem
solved. trying to find the parts you need and then buying and installing
them will cost you more than you think. Updating is usually cheaper. Unless
of course you are doing a correct restore on a vehicle.
