Hello! I've been investigating putting on a Z28 front spoiler on my car and came across a curious question- Did 74's have front braces installed for the spoiler? You can see what I'm talking about below - Here is what I believe to be a survivor 1974 Z28 front valance and spoiler. Now here is a pair of NOS braces which the seller states go to a 74-77 car with the front spoiler. I've searched my pictures of survivor 1974 Z's and can't seem to find a single car that has these braces in place. Granted I know this is a very common part to hit curbs and be replaced, so maybe they were forgotten when the spoiler was replaced? Or, maybe they were only used for a short amount of time. Maybe early 74's only? Only used on 77's? Any input would be greatly appreciated! Pictures of survivor cars would be ideal. Thanks!
