I went to vato zone and they said I could not even try the adapter, because electronic items can not be returned

So I went to oriely and they only had one GM, and it does not work

auto zone had 2

so is there like a list of part numbers that I can look up that will work or something?

 

Adapter, why ? I added a stubby antenna on my hhr.. no problem-o..

 

Well i have an aftermarket head unit and the stock antenna plug does not fit

 

Why don't you just take your new head unit and the stock head unit into the store with you? That way you can look at the adapters and compare them to what the stock antenna required, and to what the new unit requires.

 

you need a Chrysler antenna adapter
