On my 1963 with 350/290 hp crate motor, the stud, pin or metal bracket that holds the spring on the exhaust heat riser valve has rotted away. Is there a way to replace this stud and the spring mechanism? Has anyone drilled the remnants of this stud out and put in a threaded stud? Is this more work than its worth?! The valve mechanism seems fine and opens and closes freely by hand.
Thanks,
Rob
