Hi again Steve,
I don’t know if you have already placed a bid or not, but be certain that it is for an Airstream. There are other Bargman locks that are identical except for the length of the bolt. If you buy an ordinary Bargman, it will fit just fine, but the bolt will not extend out of the door. It just hides in the hole.
You’re probably wondering how I know this.
Fortunately I bought it locally from a dealer I did a lot of business with, so return was no problem.
On another topic, this is my 500th post. Rivet Master status at last. Glad it was for a worthwhile cause rather than a gratuitous self-congratulatory post. Celebrate with me.
Best of luck,
