I believe Delco slowly moves up the years dropping things from the lists, pretty much the oldest actual Delco available now is mid-late 60's, but it's sometimes the case that some items listed for newer applications [and other makes] are actually the same part that was previously listed/sold for earlier GM vehicles, like the rotor discussed above .... but all the tuneup stuff for the 235 is available from NAPA around here, don't see why anyone would want to order something from a distant source and have the problems involved with returning a defective or incorrect part
also, rotors, caps and other ignition parts don't have a makers name emblazoned on them anyway and Standard being such a major brand, even stuff in Delco boxes could be from Standard
