Door lock

[steef]

Hallo GMC-eigenaar
I am looking for an original gmc door lock with key for my 1978 palmeach motorhome

I believe the door lock is still available as a truck part from Kenworth or Peterbuilt, but I can't seem to put my finger in that info. I do have this:

Tumbler Kenworth 30GN15

Here is a link to a document on the keys and locks used on the GMC. It may help you repair yours.
