Ok guy's, I figured you all could help me before anyone else. I'm looking for the size of bolt that holds the throttle cable to the firewall on my 69 Mustang. It's doesn't come with any in the AMK kits but I'm sure I could just pick one out of the catalog, Problem is, I'm not sure of the one to pick. To bad I don't have a donor car or I could pull to from it. I know it's a stretch but can anyone help?
