Missie,
If they are the large green and orange top hat cams they fit some of the 158-xxxxxx series of machines. However I can't say off the top of my head which ones. I have 158-17570 that uses them.
The large top hat cams came in several colors; green, orange, pastel light blue, beige and as long as the numbers are the same, so is the pattern the cams make.
I use cams of all those colors on my machine and they work fine.
