[Suburban-Marco]

Hi all,
I'm Marco from Berlin, Germany.
I cannot remember the last Post post I set here. It must been a lang time ago.
I own a 84' Suburban since 25 years, I restored 10 years ago.
For some reason, which I cannot explain, my original locking cylinder for my power window/tailgate was stuck at some time years ago.
It means, the small pins in there were something like glued. I tried all to get it working again. But all failed.
So, now I am hardly searching for a replacement part. Of course I would need at least one working key with it.
Does anybody know a supplier, ob something else, where I could get a working Locking cylinder?
LMC, etc doesn't offer that part, I think..

I hope somebody has an idea, or an old one in stock, which I could buy.
So, I hope for help..
Greetings Marco
