It’s a custom throttle cable linkage, cause the original was bum as fuck and wouldn’t properly mount to my Holly carburetor. Total parts probably in the range of $22-$25. Well worth it if you ask me.
This one looks sweet and works really well! I still have to fine tune the exact length then cut a section of brake line to cover the threaded rod so it doesn’t rust.
A little glamour shot cause why not:
