What does x1 on the end of a part number mean?

Is it an interior trim piece? That usually states the color.

Lots of times a part is the same except in length or color.

There is no mention of x1

Go to the Body section and look at the interior trim parts.

For example, the part number for taillight housing screws on my 57 Commander is 3033x2. The x2 does not mean quantity as the car requires 4.

For hardware, such as a screw, as Mike stated in Post #3, it is the length of it.

I previously asked if it was for an interior trim piece where the 'x-number' suffix refers to the color. It really helps if one can be more specific in the first place.

The info above is mostly correct. An X suffix indicates that the item is a member of a family of similar parts that differ in some (usually one) way. For interior parts, the difference is likely to be color, but could be trim. For hardware, it will be the length or other measurement of the item. Some families are quite large. The 41X body washers have suffixes that go into the middle three digits. They vary in metal gauge, hole size, and/or diameter.
