Les, you aren't going to find a Monza catalog, they don't exist. And like Roy said, Camaro arm rest/door pull LOOK the same, but they don't have the hole for the lock mechanism. Only the Corvette has that provision.
see this thread we started about this before:
viewtopic.php?f=1&t=28296&p=149538&hilit=door+pull#p149538there are repair kits available, but it is just the "handle" section, and it won't look like one piece when finished.
As these are a common item that broke/breaks, you could keep looking and asking for the part.
Which side and what color?
Good luck and have fun.
cheers jer
