IF your jacket has a Plastic MOLDED TOOTH Zipper:
Jackets usually have either a #5 or #8 molded plastic zipper in them. And yes, some are even a #10 molded, but not normally.
This particular zipper head is found in reversible jackets or pant legs.
There is NOT a "wrong" side, hence no numbers on your zipper head.
The head is the same on both sides with the zipper pull that runs over the top on a "u" track.
If you can't determine what sort of zipper head you need to replace, text me a picture of your zipper at the BOX & PIN end (bottom). Also with a picture of the zipper head. I'll see if I can identify it.

PLEASE understand that there are THOUSANDS of broken zippers out there!
I get over 100 texts per day, 200 phone calls before 10am in Colorado & yes, over 1,000 emails a DAY.
Please do NOT call! Either text or email pictures!
I will send you back a link to my website for the zipper head that I think is correct.
If you text on weekends, I'll respond on Monday.
I personally answer all these missives. PLEASE be patient!
I am HAPPY to give you my expertise from 60 years of replacing zippers & 34 years of being the Zipper Lady. But you need to know, I DON'T KNOW EVERYTHING & I'm just giving you my best guess.
