Need rear window gasket for 1-piece glass

[Billabob]

These are getting hard to find, will gladly pay a fair price for one that isn't crumbling to dust. Not sure if a 3-piece window gasket will work

The 3 piece and one piece should be the same. I haven’t had both glass in my possession to confirm but it shouldn’t be much different from each other. Can’t imagine AMC spending that much money to have two different sized glass for one hole. 
That being said I do have two of those weatherstrips/gaskets.

They are the same. I do have one maybe two available. I will send you a private message.
