It did not matter what it was that you ordered from GM. All they

part number and it was yours to keep, or return if you had enough
return reserve built up and if it was flagged as returnable that
month.
It was strictly the dealer's responsibility to decide if the part
being ordered was correct or not. I typically had 15 to 20 special
order parts per week and if you were familiar with a GM catalog
before the 90's it was a wonder that any special order part could be
ordered correctly. The Japanese on the other hand had a picture
with a number that corresponded to a listed specific part number.
GM's pictures merely gave you a vague description and a hint as to
where to look in the catalog.

Typical Detroit arrangonce.

And they still don't get it.
