Fellas,
I’m back to doing what I’ve always done i.e. using two screws albeit at an angle to installing Kadee 801’s. While the 2mm tapped holes are .035” closer than what the Kadee template requires, using 2X12mm screws enables enough slop to make it work. While I HATE doing this, the end result works. Analogy: Using a sledgehammer to crack eggs is ridiculous, in the end, it too also works.
These newer Atlas cars with the aforementioned Zamak frames have two bosses that are tapped for the screws which are .050” above the base of the frame. (See pictures) I’ll assume the bosses were cast so as to discourage re-drilling new holes.
I found that using Marty Milner’s .025” laser-cut shims enabled the perfect height though I did trim some off the front to help keep it hidden.
