I have a 65c10 with 283v8 2bbl. when I removed the carb. I realized one stud was missing. after further inspection, there is a little rod where stud should be. could this be a rusty and rotted stud? Ive never seen a 3 stud carb. with a 4 hole pattern. any help would be great, I'm rebuilding the carb. tomorrow. Thanks Brett
