I need some tow hook info

[pritch]

I saw some tow hooks on a 72 Blazer in a pic & pull today, but they didn't look right to me, at least nothing like what I've seen for the trucks. Are they the same, or is the Blazer type different. These didn't have any twist to them, and didn't come to a point at the end. I didn't have my camera with me. I didn't want to spend an hour trying to get them if they are just some after market thing, but I'll go back if they are real. Any pictures of 72 Blazer tow hooks out there?
