Buds53,
Can you provide more info on what truck/engine/carburetor you are working on please???

Would also help if you provide a little larger picture of the carb and linkage.
Using your Bolter title, I figure you may be working on a 1953 truck and from what can be seen in the pic, possibly a 235 with a Rochester B?
The throttle linkage in your picture seems to be from a later truck/engine (maybe a later 230/250/292???) as it doesn't match with diagrams found in this
later on-topic conversation thread that show a 235 with a Rochester B.
Hopefully with more input from you we can figure out what you have/need.

Dan
