the rope will seal up most of the 1/8" gap you are refering to, and the bolts will pull the center of the base up against the boiler to take up the rest of the gap. Mine had a few gaps too, but pulled up just fine with the bolts, just do it a little at a time, and use good hardware.
The fan box on my boiler had drop in bushings, I guess the fan box is different for the 130M. Mine had a little play, but nothing excessive, just don't tighten belts tight, like the instal direction say. My fan dirve belt is just slightly floppy, you don't need more tension. a tight belt will burn up the bushings.
Take a look at the lower lip of the burn pot/tube, just under the inspection port. Mine was pretty badly erroded from heat and fire. I had to rebuild the lip with a strip of Stainless Steel. This lip had been replaced once before in the previous 57 years, so it must be a common wear point.
It is looking good. I bet you can't wait to get it up and running.

In the install directions found here: http://nepacrossroads.com/post17025.html#p17025 you will find the instructions for this adjustment. Once you mount everything up, you will see that the 1/8" gap around the fan shaft is needed. No gasses seep out this gap, the slight draft pulls air through the gap when the motor is not running.
I would also read the install instructions about the paint. I think the silver paint acts as a heat reflective layer to keep the boiler heat in the boiler. I did an experiment many years ago with painting a radiator flat black and one silver, the flat black one radiated more heat, and had lower water temps inside than the silver painted one. Something to think about.
Take care, the boiler is looking good!! Inspect the fan itself for cracks, mine had a crack that needed to be TIG welded.

are you looking for the motor mount for the AA?
