Central Locking Module, Airbag Sensor

My van drowned last year on the beach in France, salt water got into just about everything. I rewired the entire van and the only two things missing is the Central Locking Module and the Airbag Sensor under the drivers seat.
My Garage ordred the CL-Module by GM-USA quite a while ago and they still can't tell me when they will be able to deliver it. :banghead:

So i'm looking for a second hand CL-Module and Air-Bag Sensor.
If anyone has these parts lying around or knows where to get'm from, please notify.

It's a Astro 97 4.3 AWD

Cheers
