I want to know if anyone has OD diameter of the post the idler pulley mounts over on the f-body alt bracket? odd question I know but I have a new truck pulley and when I took the rear spacer off of it it looks like it may work but I don't have the alt. bracket in my hands yet to check

so.... if some one could do a real nice thing and measure the OD of the bracket mounting boss I will know if I can save some cash and get this one to work on it
