I got my judging sheet back today. Thanks Hulon.
I see I got dinged on engine belts. Since I only have one belt I know which one at least. I went and looked at the belt. Looks like new so that's not the issue. Two possible issues though. First, the belt has "Made it Mexico" all over it, yikes. Shame on me. Probably not correct for a 1958 American car. The other issue might involve the inside cogs on my belt. Are cogged belts allowed for 1958 American cars? I need to know before I buy a new Made in USA belt.
