By the name of the category it is obvious that these converters
come from GM vehicles. There are rarely flanges on these
converters and their heat shield patterns are typically a cheese
grater style. There are also other styles without heat shields that
are bulb like or round and these look similar to a small diesel.
The letters AC are often stamped on most of these converters.
