Hi guys I'm new to the site , but I have owned several Camaros , all 68s . I currently have a 68 that I recently bought and was told that it was a SS , but several things point to it not being one and I am investigating further into that . That is not why I posted , I owned a true 68 SS that I sold in 2000 , Corvette Bronze , 350 , PG , 12 bolt ect... , but while restoring it I came across a interesting thing in my assembly manual . The small block SS cars had a brass block in the brake line that was located about the middle of the drivers door and bolted to the side of the subfame . The page that it was on was in the SS350 section and had a drawing noting the difference between the 327 and the 350 cars with the 327 cars being straightlined and not having this block at this point . My 68 SS had this block . This is not written in stone but may be another piece of the puzzle in determining true linage of these cars . I will scan this page and post it for ya'lls enjoyment . Terry
