Welcome to genvibe!
For the weatherstrip that is attached to the door itself (not the one attached to the door frame)
It looks to me that the GM part numbers are
88969774 right side
88969775 left side
I don't see any right side ones anywhere, but there is a left side one on ebay for $133 at
https://www.ebay.com/sch/i.html?_from=R ... 5&_sacat=0
There is a reasonable probability that the same part from a Toyota matrix would fit, but I can't guarantee that. The Toyota part numbers for those are
67861-01040 right side
67861-01050 left side
The toyota parts list says there are 13 retainer clips per side, for some reason different parts per side, with part numbers
67867-01030 right side
67868-01030 left side
On GM parts sites they all say the weatherstrip is discontinued, but they also seem to say that the retainer clips are included with the weatherstrip. I don't see that on Toyota part sites. How many you might need depends on if the weatherstrip includes them, and if not, how many are reusable after you take the old weatherstrip off
As I said, I can't guarantee the Matrix parts will fit the Vibe. If you decide to try the Matrix parts, maybe buy one from a Toyota dealer, after first verifying that if it doesn't fit you can return it. If it works, then buy the second one with more confidence, and let us know how it turns out.
and a final repeat disclaimer. I think this info is correct, but its your money, not mine, and I'm just a random person on the internet, so factor that into your risk assessment
