Hi, I am looking at your 90-005 and 90-009. Are they interchangeable or am I "hosed" if I order the wrong one. I think that the 90-005 is the one I need according to your picture (it has no ridge along the edge of the lock piece......).

Good morning, and thanks for posting! I agree: this lock appears more similar to our 90-005. The major difference between this and the 90-009 is the lock piece, or "tongue." That ridge makes a surprising difference depending on what keeper you have.
