I have a window winch (not shure if its called that way...anny way the part on wich u crank the windor up or down) wich is not "lockable". I couldn't find picktures of one that can lock. Does anyone know if there is a option to get the tailgate locked?? Or where i can find a crank/winch that can be locked??

It's for my 1980 K5 Silverado

 

Even if you have the manual rear tail gate window, you should have a lock in the center of it. If you do not, you can pickup the lock and associated components from LMCtruck.com.

 

Well i have a lock in the crank. The guy who sold me the car magically locked it and i don't have the key. The only keys i have are for the ignition cylinder. I'm looking on ebay for some cylinders all around. Just change it all and i just need one key. Bit of a dumb action of that guy who sold the car to me.
I'ts a 140km drive to get to him so i'm cheaper buying some new.

Next problem is the rear window regulator, it's bent so i need a new one. couldn't find one at rockauto but lmc got them. 100usd and the the shipping. I'd better try to find one in the netherlands. Shipping kills me every time....
